Abstract:
1. A curable composition, comprising: a polyether polymer (A) containing a reactive silyl group represented by the following formula (1); and at least one of a polyether polymer (B) containing a reactive silyl group represented by the following formula (2) and a (meth)acrylic polymer (C) containing a reactive silyl group represented by the following formula (3): wherein R 1 is a methoxymethyl group; R 2 represents a C1 to C20 hydrocarbon group, a C6 to C20 aryl group, a C7 to C20 aralkyl group, or a triorganosiloxy group represented by R 0 3 SiO— wherein each of three R 0 s is a C1 to C20 hydrocarbon group and they may be the same as or different from each other; X represents a hydroxy or hydrolyzable group; W represents a linking group selected from —O—R 8 —, —O—CO—N(R 9 )—, —N(R 9 )—CO—O—, —N(R 9 )—CO—N(R 9 )—, —S—CO—NH—, —NH—CO—S—, and —S— wherein R 8 represents a divalent C1 to C8 hydrocarbon group, and R 9 represents hydrogen or a C1 to C18 hydrocarbon group optionally substituted with halogen; in the case that W is —O—R 8 —, a is 1 or 2, b is 0 or 1, and c is 1 or 2, provided that a+b+c =3 is satisfied; in the case that W is a group other than —O—R 8 -, a is 0, 1, or 2, b is 0, 1, or 2, and c is 1, 2, or 3, provided that a+b+c=3 is satisfied; and in the case that a plurality of R 1 s, R 2 s, or Xs exist, they may be the same as or different from each other, wherein R 2 and X are defined as mentioned in formula (1); V represents a divalent C2 to C8 hydrocarbon group; d represents any of 0, 1, and 2; and in the case that a plurality of R 2 s or Xs exist, they may be the same as or different from each other, and wherein R 1 , R 2 , and X are defined as mentioned in formula (1); Z represents a linking group selected from —CO—O—,—O—CO—N(R 9 )—, —N(R 9 )—CO—O—, —N(R 9 )—CO—N(R 9 )—, —S—CO—NH—, —NH—CO—S—, and —S— wherein R 9 is defined as mentioned in formula (1); n represents a number of 1 to 8; a is 0,1, or 2, b is 0, 1, or 2, and c is 1, 2, or 3, provided that the condition: a+b+c =3 is satisfied; and in the case that a plurality of R 1 s, R 2 s, or Xs exist, they may be the same as or different from each other.
