Abstract

The swelling of a nematogenic elastomer by an isotropic solvent was earlier predicted (Macromolecules 25, 445 (1992)) to be more complex than that of a classical elastomer. We extend here to the swelling by solvents having a nematic‐isotropic transition in the pure phase in the region of that of the pure elastomer. The phase diagrams are qualitatively different from the first case, but still with the novel features of a triple point and a gel‐gel biphasic gap reported in the initial study. Where the cross‐coupling is stronger than the self‐couplings we have an azeotropic point.

## Abstract Sorption of liquids by elastomers is advanced as a means of studying polymer structure. Liquids represent a wider versatility in this regard over vapors since they allow choices of molecular sizes, shapes, and configurational distributions, and thermal effects not available with vapors.

The behavior of a polybutadiene-carbon black composite entering into contact with organic solvents and gasoline was investigated. The composite used has a conductivity of 3.0 { 0.1 V 01 cm 01 . However, if it comes into contact with organic solvents (gasoline, for instance) the matrix absorbs them a

## Abstract The phase behaviour of binary nematogen mixtures of side‐chain liquid crystal crosslinked polymers and low molecular weight liquid crystals is investigated with particular emphasis on the effects of nematic coupling. The cross nematic quadrupole parameter ν~12~ is assumed to be proporti
