Document Type and Number:
WIPO Patent Application WO/2022/260058
Kind Code:
A1
Abstract:
Provided is an adhesive composition containing 5-250 parts by mass of liquid farnesene rubber (B) and 10-500 parts by mass of a tackifying resin (C) per 100 parts by mass of at least one solid rubber (A) selected from the group consisting of natural rubber, polyisoprene rubber, polybutadiene rubber, styrene-butadiene copolymer rubber, styrene-isoprene copolymer rubber, acrylonitrile-butadiene copolymer rubber, chloroprene rubber, ethylene-propylene rubber, and butyl rubber, the liquid farnesene rubber (B) satisfying requirements (I) and (II). (I) The melt viscosity measured at 38°C is within the range of 0.1-3,000 Pa∙s. (II) When measured using gel permeation chromatography (GPC), the maximum peak molecular weight (Mt) is 3,000-200,000, and the molecular weight distribution (Mw/Mn) is 1.0-1.4.
