摘要: Block copolymers having a repeating unit comprised of polysiloxane and urea segments are prepared by copolymerizing certain diaminopolysiloxanes with diisocyanates. The invention also provides novel useful as precursors in the preparation block method making such diaminopolysiloxanes. Pressure-sensitive adhesive compositions comprising copolymer provided sheet materials coated same.
