Abstract
A curable polymer composition comprising PA1 (A) an alkyl (meth)acrylate base polymer having a silicon-containing reactive group, PA1 (B) an oxyalkylene base polymer having a silicon-containing reactive group, PA1 (C) a silicon-containing compound having three or four hydrolyzable groups bonded to the silicon atom, PA1 (D) a silicon-containing compound having two hydrolyzable groups bonded to the silicon atom and PA1 (E) a curing accelerator wherein the compounds (C), (D) and (E) are contained in amounts of 0.01 to 30 parts by weight, 0.1 to 30 parts by weight and 0.01 to 10 parts by weight per 100 parts by weight of the total amount of the polymers (A) and (B), which composition has improved storage stability while a cured material therefrom has good mechanical properties, particularly elongation.
