ABSTRACT:
Improved plasticizer resistant pressure sensitive hot melt adhesive compositions are prepared by incorporating in the adhesive polymer, tackifying resin and oil 5 to 70% by weight of the adhesive of a core shell modifier comprising a crosslinked rubbery core and a glassy thermoplastic polymer shell, the core being crosslinked by the presence therein of up to 5% by weight of a polyunsaturated monomer having two or more non-conjugated sites of unsaturation of unequal reactivity.
