High Temperature Elastomers: Glass Transition-Structure Correlations for Two Systematic Series of Linear Poly(Carborane-Siloxane)S. II. Incompatibility.
Abstract
Previously reported results related glass transition temperature to structure in two systematic series of poly(carborane-siloxane)s using a well known copolymer composition-glass transition relationship. The relationship was originally proposed to apply not only to copolymers, but also to diluent systems. Accordingly, mixtures of polymers within each series were prepared and the thermomechanical spectra were determined by the technique of Torsional Braid Analysis. The binary mixtures included polydimethyl-siloxane with polymers in both series and a mixture of two -CB10H10C- siloxane polymers. In all cases, the thermomechanical spectra revealed only those transition regions characteristic of the individual components. (Author)
