摘要:
The invention provides an acrylic resin-based transparent substrate having an alignment layer spread thereon, wherein the photo-alignment layer and the substrate are kept tightly bonded to each other. The invention also provides a layered body having an acrylic resin-containing transparent substrate and, as formed on one surface of the transparent substrate by spreading and bonding thereto, a photo-alignment layer containing photo-responsive molecules capable of responding to light. According to the invention, there can be provided an acrylic resin-based transparent substrate having on the surface thereof, a photo-alignment layer having excellent adhesion force and containing photo-responsive molecules capable of responding to light.
摘要:
A continuous process for producing high pressure polyethylene is described. The process includes contacting first amounts of ethylene, an optional polar comonomer, and a first C2 to C12 modifier in the presence of a first amount of initiator in a reaction system under polymerization conditions to form a reaction system effluent comprising a first polyethylene resin having a first concentration of unreacted monomer therein; and directing an ethylene stream and the reaction system effluent to a pressure separation unit operated at separation conditions thereby removing at least a portion of the unreacted monomer from the reaction system effluent.

Disclosed herein is an optical information recording disk comprising as a base material thereof a polymer or copolymer having a glass transition temperature of at least 50.degree. C. and a structural unit derived from a monomer which is an ester of an .alpha.,.beta.-unsaturated carboxylic acid and an alicyclic alcohol represented by the general formula: ##STR1## wherein n is an integer of 1-5, R denotes a hydrogen or an alkyl or alkenyl group, and, when n stands for an integer of 2-5, the Rs may be the same or different.The above disk does not develop deformation such as warping or twisting by changes in humidity and is uniform optically.
摘要:
The invention relates to a radiation curable coating which provides superior abrasion and chemical resistance and excellent adhesion properties. The coating is produced by radiation curing. A first monomer selected from the group consisting of triacrylates and tetracrylate mixed with a second monomer having an N-vinyl imido group, preferably an N-vinyl lactam, such as vinyl pyrrolidone or vinyl caprolactam. The monomer mixture is substantially oligomer-free and if the radiation is ultraviolet light, a photoinitiator, preferably p-phenoxydichloro acetophenone or dimethoxyphenyl acetophenone, is included in the mixture.
