Title:
反応性ケイ素基含有重合体、および硬化性組成物
Document Type and Number:
Japanese Patent JP7249998
Kind Code:
B2
Abstract:
Provided are a reactive silicon group-containing polymer and a curable composition containing said polymer, that: provide a cured product having a low modulus, flexibility, and excellent tensile strength, tensile elongation, and tear strength; and exhibit excellent rapid curing properties even when a low-activity catalyst has been added. In the reactive silicon group-containing polymer, a reactive silicon group indicated by general formula (1) is bonded to the molecular chain of the polymer and an atom adjacent to the reactive silicon group has an unsaturated bond. General formula (1): -Si (R1)3-a(X)a(in the formula, R1 each independently indicate a C1-20 hydrocarbon group, the R1 hydrocarbon groups can be substituted and a hetero-containing group can be used, X is a hydroxyl group or a hydrolyzable group, and a is 1, 2, or 3.)
