Abstract
Crosslinked random acrylate-ureadiacetoacetamide-diacetoacetamide copolymers are disclosed. These copolymers are prepared by the reaction of at least one polyfunctional acrylate with at least one ureadiacetoacetamide and at least one diacetoacetamide in the presence of a catalyst capable of promoting the reaction between the polyfunctional acrylate, the ureadiacetoacetamide, and the diacetoacetamide. In a preferred embodiment, the copolymers are employed to produce wear layer compositions for surface coverings.
