ABSTRACT:
A method for reacting a methylene-containing component such as an acrylic polymer prepared from acetoacetoxyalkyl (meth)acrylate and an alkene-containing component such as a polyfumarate, polymaleate, a polyester containing both fumarate and maleate groups or a polyacrylate comprises the reaction of a tertiary amine such as triethylene diamine and an epoxide such as a glycidyl-functional (meth)acrylic polymer in the presence of the methylene-containing component and alkene-containing component. The tertiary amine can be incorporated into the alkene-containing component such as the reaction of an unsaturated polyester with a compound having both tertiary amine and primary or secondary amine groups. The tertiary amine can be incorporated into the methylene-containing component such as an acrylic polymer derived from a tertiary amino-functional monmer and acetoacetoxyalkyl (meth)acrylate. The epoxide can be incorporated into the methylene-containing component such as an acrylic polymer obtained from glycidyl (meth)acrylate and acetoacetoxyalkyl (meth)acrylate. The epoxide can be incorporated into the alkene-containing component.
