Abstract
A rubbery copolymer of butadiene, styrene and acrylonitrile, if desired, with a tensile strength of about 50 to about 100 psig containing a minor amount of styrene, particularly in combination with selective tackifier resins. Said copolymer is preferably prepared by a step-wise aqueous emulsion polymerization with styrene and modifier being incrementally added. Said rubbery copolymer/tackifier mixture is particularly useful as an adhesive.
