Dynamic mechanical and thermomechanical properties of silicone‐polycarbonate block copolymers

Representative random, alternating block copolymers of polydimethylsiloxane (PDMS) and bisphenol‐A‐polycarbonate (BPAPC) were studied by thermomechanical and dynamic mechanical techniques. Data on glass transition temperatures (Tg), heat‐deflection temperatures (Td), Vicat softening temperatures (Ts), coefficients of linear expansion (α), stress‐strain, and stress relaxation for four PDMS‐BPAPC block co‐polymers are presented. The effect of casting films from mixed n‐hexane‐methylene chloride solution on the thermomechanical and dynamic mechanical properties was also studied.
