BLOCK COPOLYMER HYDRIDE AND LAMINATED GLASS

Title:

BLOCK COPOLYMER HYDRIDE AND LAMINATED GLASS

Document Type and Number:

WIPO Patent Application WO/2016/104740

Kind Code:

A1

Abstract:

The present invention is a block copolymer hydride (D) which is obtained by hydrogenating a block copolymer (C) that is composed of two or more polymer blocks (A) that are mainly composed of a monomer unit derived from an aromatic vinyl compound and one or more polymer blocks (B) that are mainly composed of a monomer unit derived from a chain conjugated diene compound. This block copolymer hydride (D) has a low-temperature-side tan δ peak temperature within the range of from -20° to 20°C and a high-temperature-side tan δ peak temperature at 100°C or more with respect to the dynamic viscoelasticity characteristics. This block copolymer hydride (D) is obtained by hydrogenating 90% or more of all the unsaturated bonds, namely, carbon-carbon unsaturated bonds in the main chain and side chains and carbon-carbon unsaturated bonds of aromatic rings of a block copolymer (C) wherein: if wA is the weight fraction of the polymer blocks (A) in the whole block copolymer (C) and wB is the weight fraction of the polymer blocks (B) in the whole block copolymer (C), wA:wB is from 15:85 to 40:60; and the content ratio of structural units derived from 1, 2- and 3, 4-addition polymerization in the structural units derived from chain conjugated diene compounds in the polymer blocks (B) is 40% by weight or more. In addition, this block copolymer hydride (D) has a weight average molecular weight of 40,000-200,000.
