Addition products prepared from mercapto-functional polyhydric alcohols and vinyl-type silanes containing hydrolyzable groups |
摘要 |
Disclosed is a free-radical addition product of a mercapto-functional polyhydric alcohol and a vinyl-type silane having at least one hydrolyzable group directly attached to a silicon atom, the addition product prepared by reacting the mercapto-functional polyhydric alcohol and the vinyl-type silane in the presence of a free radical initiator. The addition product contains at least two hydroxyl groups bonded to carbon atoms and at least one silicon atom bonded to at least one hydrolyzable group. The resulting polyhydroxyl-functional addition products can be chain extended using organic polyisocyanates to produce isocyanate-terminated compounds which also contain silicon atoms directly bonded to hydrolyzable groups along the molecule chains.
