摘要：

A liquid crystalline main-chain polymer was slightly crosslinked by a reaction with α, ω-difunctionalized oligo-siloxanes. Crosslinking does not disturb the liquid crystalline phases, which are identified by x-ray measurements as smectic B and smectic A phases. Measurements of the elastic properties of the crosslinked sample show rubber-like elasticity, even in the liquid crystalline phases. A difference of 7 K was found between cooling and heating for the smectic A/isotropic transition from DSC and mechanical measurements. © 1990 Steinkopff.
