<p>A novel class of vinyl polymers containing silicons having in its molecule at least one constitutent unit of the formula <CHEM> wherein R<1> is a substituted or unsubstituted monovalent hydrocarbon residue; R<2> is <CHEM> R<3> is hydrogen or methyl group; R<4> is a substituent directly bonded to silicon atom and is selected from a substituted or unsubstituted alkylene, or a substituted or unsubstituted alkylene containing hetero atoms; m and n each is a positive number, which will fulfil the requirement of 2 </= m+n </=4; A is a direct bond, - @-O-R<5>-, -@-, -@-NH-R<6>, phenylene or substituted phenylene; B is - @-O- or -@-@-; R<5> and R<6> each represents an alkylene, providing that when A is- @-O-R<5>- , m+/-n is 2. The present vinyl polymers are very useful in various technical fields including preparation of lens and other molding products, paints and various instrial resins.</p> |
