Patent ID: 7932325

Claim:
A telechelic polymer comprising the reaction product of a Michael donor component, a polyacryl Michael acceptor component, and ethylenically unsaturated monomer having a reactive azlactone functional group, wherein said Michael donor component corresponds to one of formulas (I), (II) or (III): (W 1 —CHR 1 —C(O)) x —P (I) (W 1 —NH—C(O)) x —P (II) W 1 —CH 2 —W 2 (III), wherein R 1 represents hydrogen, an alkyl group or an aryl group; W 1 and W 2 each independently selected from a cyano group, a nitro group, an alkyl carbonyl group, an alkoxy carbonyl group, an aryl carbonyl group, an aryloxy carbonyl group, an amido group, and a sulphonyl group; P represents a mono- or multi-valent organic residue, or the reaction residue of a polyol or polyamine in an acetoacetylation reaction, and x is an integer of 1 or more, with the proviso that the number of donor equivalents is two or greater, wherein said polyacryl component is of the formula: R 4 —(Z—C(═O)—CH═CH 2 ) z , wherein each Z independently represents —S—, —O—, —NH—, or —NR 5 —, where R 5 is H, or an alkyl group having from 1 to 6 carbon atoms; R 4 independently represents a polyvalent organic group having a valence of z.
