WIPO Patent Application WO/2018/221468
Kind Code:
A1
Abstract:
Provided are: a synthetic rubber-based adhesive having both excellent heat resistance and excellent adhesiveness to a substrate, capable of preventing displacement or separation even under a high temperature environment, and suitable for use in a high temperature environment; an adhesive sheet; and a polishing member laminated body. The synthetic rubber-based adhesive according to the present invention comprises: a synthetic rubber (A) including a styrene-isoprene block copolymer; a tackiness-imparting resin (B); and a fatty acid ester (C) showing a weight reduction after heating at 150°C for 10 minutes of not more than 1 wt%. The amount of the tackiness-imparting resin (B) is set to 5-60 parts by weight and the amount of the fatty acid ester (C) is set to 0.1-10 parts by weight relative to 100 parts by weight of the synthetic rubber (A).
