Abstract
Acrylated silicone polymers are prepared by reacting limoneneoxide-functional silicones with acrylic acid or a substituted acrylic acid in the presence of a catalyst selected from tetraalkylurea (e.g. tetramethylurea), tetraalkylguanidine (e.g. tetramethylguanide) or mixtures thereof. Adhesion of the resulting ultraviolet light curable compositions to various substrates, especially super calendared kraft papers, can be improved with the addition of N-vinylpyrrolidinone.
