Linear (SDS) and radial (SD)x block copolymers of styrene (S) and dienes (D=butadiene or isoprene), varying in composition and molecular weight, were formulated as pressure sensitive adhesives. The morphology of these compositions was determined by e

Tackification of block copolymers of the linear ABA or radial (AB) x type, in which the center block (B) is in the rubbery state at use temperature, follows principles established for other rubbery polymers except for peculiarities of the systems int

Styrene-diene (butadiene or isoprene) block copolymers of the SDS or (SD−)x type exhibit a plateau in the dynamic storage modulus located between the glass transitions of the polydiene and polystyrene domains. When the polydiene is the continuous p

A 70 : 30 styrene-butadiene block polymer with lamellar morphology was formed into sheets with either lamellar orientation only or with both lamellar and molecular orientation. Lamellar orientation led to the expected anisotropy in modulus and streng

Steady flow and dynamic viscosities were determined for symmetrical linear and starbranched block copolymers of butadiene and styrene above their upper (polystyrene) glass transition. Block structures examined were B-S-B, (B-S-)3, S-B-S, (S-B-)3 and
