RADIATION CURABLE URETHANE (METH)ACRYLATE POLYMER AND ADHESIVES FORMULATED WITH THEM

摘要

UV curable urethane (meth)acrylate polymers of Formula (1), where: R₁ and R' are each independently hydrogen or C_1-20hydrocarbo, R₂, R'₂, R₃ and R₄ are each independently optionally substituted divalent organo group, and p is an integer from about 6 to about 100 which are useful as laminating and/or pressure sensitive adhesives are disclosed as is methods of making them. The oligomers/polymers comprise a urethane extended backbone formed by reacting diisocyanates with polyols derived from rubber oligomers/polymers.
