Reactive acrylic polymer and a method of manufacturing the same, curable acrylic polymer, a curable composition, cured product, and these applications

摘要

PROBLEM TO BE SOLVED: To obtain a new acrylic polymer in which polymer end groups are highly controlled by polymerizing an acrylic monomer in the presence of a metallocene catalyst and a thiol compound having at least one reactive silyl groups in the molecule and obtain a curable composition and a cured material from the above acrylic polymer and provide uses thereof. ;SOLUTION: This reactive acrylic polymer is obtained by polymerizing an acrylic monomer having a polymerizable unsaturated bond in the presence of a metallocene compound represented by the formula {M is a metal of the genus 4A, 4B or 5A of the periodic table, chromium, ruthenium or the like; R1 and R2 are each an aliphatic hydrocarbon group, alicyclic hydrocarbon group, aromatic hydrocarbon group or silicon-containing group which may each be substituted, hydrogen atom, single bond or the like; (a) and (b) are each an integer of 1-4; X is a hydrocarbon group or a halogen atom; (n) is 0 or an integer of [(valence of the metal M)-2] and thiols having at least one reactive silyl group in the molecule. The polymer is characterized in that the residue S-R0 (R0 is a group having a reactive silyl group) obtained by leaving hydrogen atom from thiols having a reactive silyl group is bound to at least one end of the polymer. This curable acrylic polymer, this curable composition, this cured material and uses thereof are each formed from the above reactive polymer.;COPYRIGHT: (C)2001,JPO
