Adhesive compositions comprising mixtures of block copolymers

摘要

Less expensive adhesive compositions having good adhesive properties can be achieved by combining an S-I-S or (SI)_nX block copolymers with an S-(I/B) diblock copolymer and a single tackifying resin. Furthermore, less expensive adhesive compositions can be achieved by combining S-I diblock copolymers with S-(I/B)-S or [S(I/B)]nX block copolymers and a single tackifying resin. These combinations result in lower costs of starting materials and manufacturing due to simpler processing.
