Dynamic Mechanical Analysis of Rextac Amorphous Polyalphaolefins (APAO) and Blends with Styrene Block Copolymers (SBCs), 1992 Hot Melt Symposium Proceedings

Characterization of REXTAC APAO by dynamic mechanical analysis is reported. The glass transition temperatures, Tg s were dependent on the chemical composition of the copolymers. The elasticity as measured by the storage modulus, G’, is a function of the comonomer type and concentration in the copolymer. Blending with Kraton SBCs yielded immiscible blends, as evidenced by the presence of two distinct Tg s. However, the G’ value at 25°C and 1 Hz showed varying levels of compatibility between the SBCs and APAO.
