摘要： A process is disclosed for preparing a polyacrylate-modified polyvinyl chloride processing aid for polyvinyl chloride by sequentially polymerizing the vinyl chloride and the desired acrylate ester monomer. Thus, a conventional vinyl chloride suspension polymerization is conducted at a controlled rate of agitation and in the presence of a specified concentration of suspending agent and is then halted at or near its completion; unreacted vinyl chloride monomer is removed, a minor proportion of an acrylate ester monomer, e.g., methyl methacrylate, which has been pre-mixed with a fresh supply of a free radical initiating catalyst is added and polymerization is resumed and continued until the acrylate ester monomer polymerizes in and/or on the particles of the previously polymerized polyvinyl chloride. The polyacrylate-modified PVC thereby recovered is an effective aid for processing conventional PVC, or it can be processed per se since it is suitable for calendering or extruding.

摘要： A contact lens composition, having improved dimensional stability, suitable for use in the preparation of a corrective hydrated lens or an eye bandage, comprises polymerized random graft copolymers containing (in the dry state) from 67.2 to 79.3% HEMA; from 14.25 to 35% PVP; from 0.1 to 4.04% EDMA; from 0.1 to 2.5% MA; from 0.1 to 5.0% water; from 0 to 4 ppm HQ inhibitor; and from 50 to 250 ppm MEHQ inhibitor. The contact lens composition contains from 45 to 65% water after hydration. An improved method for shaping, polymerizing, and cutting and hydrating the contact lens composition is provided. The polymerization is conducted using only a low temperature initiator, by de-gassing prior to polymerization to remove substantially all oxygen, and by conducting the initial polymerization reaction at from 23.degree. to 30.degree.C for 16 to 30 hours, during which the heat of the reaction is continuously absorbed to control the reaction exotherm. A closed, rod-shaped casting mold, lined with a polyester film material, is used and the polymeric rod obtained may be cut, machined and polished to obtain the contact lens composition. Thereafter, hydration is conducted in a buffered, 0.85 to 0.9% saline solution, at a pH of 7.0 to 7.1.
