SHAPE MEMORY MAIN-CHAIN SMECTIC-C ELASTOMERS

Page/Page column 9, (2009/10/01)
Shape memory main-chain smectic-C elastomers are described, as are methods for their preparation and monomers used in such methods. The elastomers are prepared by hydrosilylation of a reaction mixture including a liquid crystalline diene, a crosslinking agent, and a bis(silyl hydride) compound. The elastomers exhibit shape-memory properties and spontaneously reversible shape changes. They are useful for fabrication of shape memory articles including, for example, implantable medical devices, contact lenses, reversible embossing media, and Fresnel lenses.

As starting material for liquid crystalline polyesters, a number of bisarenes (arising from the diols hydroquinone, 4,4'-biphenyldiol, 1,6-di(4-hydroxyphenyl)hexane, 2,7-fluorenediol and 2,7-fluorenonediol) have been synthesize
