Claims
- 1. A polymer comprising an acrylic acid ester moiety of formula (I) as repeat unit: ##STR9## wherein R.sup.1 represents hydrogen or a methyl group; R.sup.2, R.sup.3, and R.sup.4 each represent hydrogen, an alkyl group having 1 to 4 carbon atoms, a benzyl group, a phenyl group, a phenoxyl group, chlorine or bromine; n is an integer of 1 to 4; m is 0 or 1; and k is 0 or 1.
- 2. The polymer as claimed in claim 1, wherein in formula (I) R.sup.1 represents hydrogen or a methyl group; R.sup.2, R.sup.3 and R.sup.4 each represent hydrogen, an alkyl group having 1 to 4 carbon atoms, a benzyl group, a phenyl group or chlorine.
- 3. A crosslinked polymer comprising an acrylic acid ester moiety of formula (I) as repeat unit and an HO-group-containing repeat unit: ##STR10## wherein R.sup.1 represents hydrogen or a methyl group; R.sup.2, R.sup.3, and R.sup.4 each represent hydrogen, an alkyl group having 1 to 4 carbon atoms, a benzyl group, a phenyl group, a phenoxyl group, chlorine or bromine; n is an integer of 1 to 4; m is 0 or 1; and k is 0 or 1, crosslinked by an isocyanate compound.
- 4. The crosslinked polymer as claimed in claim 3, wherein in formula (I) R.sup.1 represents hydrogen or a methyl group; R.sup.2, R.sup.3 and R.sup.4 each represent hydrogen, an alkyl group having 1 to 4 carbon atoms, a benzyl group, a phenyl group or chlorine.
- 5. The crosslinked polymer as claimed in claim 3, wherein said HO-group containing repeat unit has the formula ##STR11##
