Polymers of acrylic esters containing amide groups

摘要

The invention relates to a polymer (for example (I)) having at least one group derived from a carboxylic ester of a hydroxyalkylamide group, in which the carboxylic ester is derived from an alpha , beta -ethylenically unsaturated carboxylic acid and a radiation curable composition comprising this polymer. A coating composition comprising this composition has a high rate of polymerisation and shows the desired chemical and mechanical properties.
