Abstract

A method for the loading and alignment of liquid crystal polymers in electro-optic and electro-active devices by in-situ polymerization between substrates of liquid crystal monomers. The molecular weight of the resulting liquid crystal polymer is controlled by the addition of a chain transfer reagent, for example, a thiol-containing compound which may be a liquid crystal material.
