Claim:
1. A composition for forming a curable polymer composition comprising: (A) a polymer having at least a reactive silyl group; (B) a crosslinker or chain extender; and (C) a condensation accelerator comprising a guanidine-containing compound, wherein the guanidine-containing compound comprises a plurality of guanidine functional groups, the guanidine-containing compound being chosen from a compound of the formula (i) or (ii): where R 9 , R 10 , R 11 , and R 12 are independently chosen from an alkyl, a substituted alkyl, an alkenyl, a substituted alkenyl, an alkynyl, a substituted alkynyl, a carbocycle, a heterocycle, an aryl, or a heteroaryl; and R 13 is chosen from an alkylene, a cycloalkylene, an alkynylene, an alkenylene, an arylene, a siloxane derivative, or a polysiloxane derivative; where R 14 , R 16 , R 17 , R 18 , and R 19 are independently chosen from hydrogen, an alkyl, a substituted alkyl, an alkenyl, a substituted alkenyl, an alkynyl, a substituted alkynyl, a carbocycle, a heterocycle, an aryl, or a heteroaryl; and R 20 is chosen from an alkylene, a cycloalkylene, an alkynylene, an alkenylene, an arylene, a siloxane derivative, or a polysiloxane derivative.
