Abstract
A coating composition comprising an anhydride polymer (A) containing at least two cyclic carboxylic acid anhydride functional groups and a polymer (B) containing at least two functional groups reactive with anhydride groups and selected from hydroxyalkylamino, hydroxyalkoxyalkylamino, hydroxysubstituted acyloxyalkylamino, hydroxysubstituted polyacyloxyalkylamino, mercaptoalkylamino and oxazolidino groups. One of the polymers (A) and (B) comprises at least one flexible polymer chain selected from polyether, polyester, silicone, diene polymer, hydrogenated diene polymer, polyurethane, polyisobutylene and polyacrylate chains. The functional groups characteristic of that polymer are each present as a terminal group at the end of a flexible polymer chain.

A coating composition comprising
- (A) an anhydride polymer containing at least two cyclic carboxylic acid anhydride functional groups and
- (B) a polymer containing at least two functional groups reactive with anhydride groups and selected from the group consisting of hydroxyalkylamino, hydroxyalkoxy-alkylamino, hydroxy-substituted acyloxyalkylamino, hydroxy-substituted polyacyloxyalkylamino, mercaptoalkylamino and oxazolidino groups,
- one of the polymers (A) and (B) comprising at least one flexible polymer chain selected from the group consisting of polyether, polyester, silicone, diene polymer, hydrogenated diene polymer, polyurethane, polyisobutylene and polyacrylate chains and having at least two functional groups present in the polymer as terminal groups separated by the flexible polymer chain.
A coating composition comprising:
- (A) an anhydride polymer containing more than two cyclic carboxylic acid anhydride functional groups and
- (B) a polymer comprising at least one flexible aliphatic polyester chain having at least two beta-hydroxy amino groups which are reactive with anhydride groups and which are present in the polymer as terminal groups separated by the flexible aliphatic polyester chain.
