Abstract
Abstract A curable polymer composition which comprises (A) a polyoxyalkylene base isocyanate compound having a terminal isocyanate group which compound is obtainable by reacting polyoxyalkylenepolyol with an organic diisocyanate and (B) a copolymer having at least one isocyanate group in a molecule on the average, the backbone of which copolymer comprises (1) repeating units derived from at least one monomer selected from the group consisting of alkyl acrylates having 1 to 8 carbon atoms in the alkyl group and alkyl methacrylates having 1 to 8 carbon atoms in the alkyl group and (2) repeating units derived from at least one monomer selected from the group consisting of alkyl acrylates having at least 10 carbon atoms in the alkyl group and alkyl methacrylates having at least 10 carbon atoms in the alkyl group, which composition provides a cured material with good weather resistance and good elasticity.
