DUAL CURING POLYMERS AND METHODS FOR THEIR PREPARATION AND USE

摘要

A polymer cures by both radiation and moisture curing mechanisms. The polymer is prepared by hydrosilylation. The polymer is useful in adhesive compositions. The polymer includes units of formulae (I), (R²2Si0_2/2)b, (R²Si0_3/2)c, (Si0_4/2)d, (R¹ )f, and (R²3SiO_1/2)g, where each R¹ is independently an oxygen atom or a divalent hydrocarbon group; each R¹ is independently divalent hydrocarbon group; each R² is independently a monovalent organic group that is free of terminal aliphatic unsaturation each X is independently a monovalent hydrolyzable group; each J is independently a monovalent epoxy functional organic group; subscript a has a value of 1 or more; subscript b has a value of 0 or more; subscript c has a value of 0 or more; subscript d has a value of 0 or more; subscript e has a value of 1 or more; subscript f has a value of 0 or more; subscript g has a value of 0 or more; subscript s is 1, 2, or 3; and subscript t is 1, 2, or 3.
