摘要
A polymer dispersed liquid crystal composite prepared from: (1) at least one multifunctional electron-rich alkene that does not undergo appreciable homopolymerization and is selected from the group consisting of (a) vinyl ethers and vinyl sulfides; (b) keteneacetals, ketenethioacetals and methylene oxathiolanes, wherein the carbon of the carbon-carbon double bond not bearing the electron donating group has bonded to it H or a combination of H and a C1 to C6 alkyl, preferably a methyl group; (c) ortho or para vinyl phenyl ethers or thioethers (also known as styryloxy or styrylthio ether monomers); or (d) bicylic alkenes which have, as a result of their stereoelectronic configuration, unequal pi -electron density above and below the plane of the carbon-carbon double bond axis; (2) a multifunctional thiol; (3) a photoinitiator; and (4) liquid crystal material.
