New N=acyl-carbamate(s) and polymers giving curable coatings with good adhesion

摘要

- N-Acylcarbamates of the formula R<1>CH=CR<2>-COO-A-O-CO-NH-CO-R<3> (I) are new (where R<1>, R<2> = H or Me or one of R<1> and R<2> = CH2-CO-O-CO-R<3>; R<3> = opt. substd. 1-10 C (aryl)aliphatic or aromatic hydrocarbyl; A = a divalent 1-10 C satd. aliphatic, aromatic or arylaliphatic hydrocarbon gp.). Also claimed are addn. polymers (II) contg. (I) units and aq. (II) dispersions or solns..
