ABSTRACT:
A method for preparing a substrate coated or laminated with a multiblock copolymer comprising endblocks of phenylbutadiene and an elastomeric midblock of a conjugated diene such as isoprene or butadiene is disclosed. The copolymer is crosslinkable by EB radiation such that the crosslinks are confined primarily to the endblock domains in the polymer with minimal crosslinking occurring in the rubbery matrix. Also disclosed are blends of the copolymers with tackifier resins compatible with the midblock regions. The blends provide a curable PSA having enhanced cohesive strength while maintaining adhesive properties.
