硬化性組成物
Document Type and Number:
Japanese Patent JP6783267
Kind Code:
B2
Abstract:
The present invention provides a curable composition having improved performance in sealing material applications, the curable composition comprising: (A) an acrylic polymer having at least two reactive silyl groups; (B) an alkylene oxide-based polymer having at least two reactive silyl groups; and (C) an alkylene oxide-based polymer having only one reactive silane group. The polymer (A) has a repeating unit derived from a (meth) acrylate monomer represented by formula (a1), a repeating unit derived from a (meth) acrylate monomer represented by formula (a2), and a repeating unit derived from a(meth) acrylate monomer represented by formula (a3). (a1) In the formula: CH2 = CX1-C (= O)-O-A1, X1 is a hydrogen atom or a methyl group, and A1 is a linear or branched aliphatic hydrocarbon group having 1-3 hydrogen atoms or carbon atoms; (a2) in the formula: CH2 = CX2-C (= O)-O-A2, X2 is a hydrogen atom or a methyl group, and A2 is a linear or branched aliphatic hydrocarbon group having 4-7 carbon atoms; (a3) In the formula CH2 = CX3-C (= O)-O-A3, X3 represents a hydrogen atom or a methyl group, and A3 represents a linear or branched aliphatic hydrocarbon group having 8-40 carbon atoms.
