Vinyl ethers of formula <FORM:0763634/IV(a)/1> and modifications thereof in which one or more of the hydrogen atoms attached to the ring carbon atoms are replaced by alkyl groups e.g. 2 : 2- and 2 : 3-dimethyl groups), wherein Z is a methylene or polymethylene group optionally carrying hydrocarbon substituents and in all not exceeding seven carbon atoms, R1 and R11 represent alkyl groups when Z is such that O and N are separated by a chain of less than 4 carbon atoms and represent hydrogen or alkyl groups when said chain exceeds 3 carbon atoms, alone or admixed with one or more monomers are polymerized in bulk, aqueous emulsion or organic solution in the presence of a polymerization catalyst. The other monomers may be acrylic and methacrylic acid, amides and esters of acrylic and methacrylic acids (e.g. methyl methacrylate, butyl acrylate), acrylonitrile, methacrylonitrile, styrene, vinyl esters or mixtures thereof. In aqueous emulsion the emulsifier may be an octylphenoxypolyethoxyethanol. Specified solvents are dimethylformamide and ethoxyethyl acetate. Exemplified vinyl ethers are 2-N : N-ethyleneureidoisobutyl vinyl ether, 4-N : N-ethyleneureido-4-methyl-2-pentyl vinyl ether and 7 - N : N - ethyleneureido - 3 : 7 - dimethyloctyl vinyl ether. The catalyst may be dimethyl, diethyl and dibutyl azodiisobutyrates; dimethyl and diethyl azobismethylvalerates; azodiisobutyramide; azodiisobutyronitrile; azobis-(a-methylbutyronitrile) and (a-methylvaleronitrile); benzoyl, methylethylketone, caproyl and cumene peroxides; tert.-butyl hydroperoxide; butyl perbenzoate; and ammonium, sodium or potassium persulphates. The polymers may be drawn into fibres and these may be after-treated with amino compounds (e.g. 2-N : N-dimethylaminoethylamine) to increase their dye affinity. Alone, in organic solution or in admixture with adipic acid polyesters (e.g. adipic acid-propyleneglycol condensate) or other vinyl ether monomers of the above formula, or copolymers of acrylic acid and methyl methacrylate, they may be cured or cross-linked with para-toluene sulphonic acid to produce hard films or insoluble gels, if required, on the surface of glass fibre. Specification 763,635 is referred to. ALSO: The invention comprises compounds of formula <FORM:0763634/IV(b)/1> and modifications thereof in which one or more of the hydrogen atoms attached to the ring carbon atoms are replaced by alkyl groups, wherein Z is a methylene or polymethylene group optionally carrying hydrocarbon substituents and in all not exceeding seven carbon atoms, R1 and R11 represent alkyl groups when Z is such that O and N are separated by a chain of less than 4 carbon atoms and represent hydrogen or alkyl groups when said chain exceeds 3 carbon atoms. R1 and R11 are preferably alkyl groups of not more than four carbon atoms and are preferably methyl groups. The compounds are prepared by reacting ethyleneimine or a substituted ethyleneimine (e.g. 2 : 2- or 2 : 3-dimethylethyleneimine) with an isocyanatoalkyl vinyl ether of formula <FORM:0763634/IV(b)/2> at a temperature of between 0 DEG and 100 DEG C. and preferably in presence of an inert organic solvent, e.g. naphtha, benzene or toluene. Specified isocyanate starting materials are 2-isocyanatoisobutyl, 2 - isocyanato - 2 - methylbutyl, 2 - isocyanato - 2 - methylhexyl, 2 - isocyanato - 2 - ethylbutyl, 3 - isocyanato - 3-methylbutyl, 4 - isocyanato - 4 - methyl - 2-pentyl, 4 - isocyanato - 4 - methyl - 1 - pentyl and 7 - isocyanato - 3:7 - dimethyl - 1 - octyl vinylethers. The examples describe the preparation of 2 - N:N - ethyleneureiodoisobutyl vinylether, 4 - N:N - ethyleneureido - 4-methyl - 2 - pentyl vinylether and 7 - N:N-ethylenureido - 3:7 - dimethyloctyl vinylether. Specification 763,635 is referred to. ALSO: Compounds for use in finishing textiles are prepared by polymerizing or copolymerizing vinyl ethers of the formula <FORM:0763634/IV(b)/1> and modifications thereof in which one or more of the hydrogen atoms attached to the ring carbon atoms are replaced by alkyl groups, wherein Z is a methylene or polymethylene group optionally carrying hydrocarbon substituents and in all not exceeding 7 carbon atoms, R1 and R11 represent alkyl groups when Z is such that O and N are separated by a chain of less than 4 carbon atoms and represent hydrogen or alkyl groups when said chain exceeds 3 carbon atoms. The comonomer is a vinyl or vinylidene compound, those specified being acrylic and methacrylic acids, and amides and esters thereof (e.g. methyl methacrylate and butyl acrylate), acrylonitrile, methacrylonitrile, styrene, vinyl esters and mixtures thereof. Exemplified vinyl ethers are 2-N:N-ethyleneureidoisobutyl vinyl ether, 4-N:N-ethyleneureido-4-methyl-2-pentyl vinyl ether and 7 -N:N - ethyleneureido - 3:7 - dimethyloctyl vinyl ether. In an example a mixture of N:N-ethyleneureidoisobutyl vinyl ether and butyl acrylate is emulsified in water containing an octylphenoxypolyethoxyethanol emulsifier and the emulsion copolymerized by treatment with ammonium persulphate and sodium hydrosulsulphite; the resulting dispersion is applied to wool in conjunction with oxalic acid, and the treated wool is dried and cured at 270 DEG F. for 10 minutes, thereby acquiring shrink resistance. The above polymers may also be reacted with cellulose or wool to modify the latter in their chemical properties without causing any change in their physical properties. Specification 763,635 is referred to. ALSO: An insecticidal composition comprises a spray oil containing as the active ingredient a vinyl ether of formula <FORM:0763634/VI/1> and modifications thereof in which one or more of the hydrogen atoms attached to the ring-carbon atoms are replaced by alkyl groups, wherein Z is a methylene or polymethylene group optionally carrying hydrocarbon substituents and in all not exceeding 7 carbon atoms, R1 and R11 represent alkyl groups when Z is such that O and N are separated by a chain of less than 4 carbon atoms and represent hydrogen or alkyl groups when said chain exceeds 3 carbon atoms. (see Group IV(a)). Specification 763,635 is referred to.
