Abstract

Abstract A compound represented by the following formula: ##STR1## wherein R is a C 3 -C 24 olefinically unsaturated organic radical having functionality which renders the nitrogen atom electron deficient, the olefinic unsaturation functionality being polymerizable, R 1 is hydrogen or a C 1 -C 4 alkyl radical, or R and R 1 together with the nitrogen atom can form an olefinically unsaturated 5 to 7-member ring which has functionality that renders the nitrogen atom electron deficient and the olefinic unsaturation functionality is polymerizable, R 2 and R 3 are hydrogen, a C 1 -C 4 alkyl or acyl radical, or R 2 and R 3 together are a C 2 -C 4 alkylene group, R 4 is hydrogen or a C 1 -C 4 alkyl, acyl, ester, amide or acid group, and n is an integer from 1 to 10, provided n is not 1 when R is (meth)acryloyl, R 2 and R 3 are methyl and R 1 and R 4 are hydrogen. Under acidic conditions the above compounds having R 1 =hydrogen afford cyclic hemiamidals and hemiamide ketals of the following formula ##STR2##
