    Abstract: Peroxide initiators are disclosed that can be used at lower temperatures during HIPS production. Enhanced formation of graft polymers between polystyrene and polybutadiene (rubber) can be accomplished by using these lower temperature peroxide initiators that have a 1 hour half-life period at one or more temperatures from 95° C. to less than 111° C. during the pre-inversion stage. “Higher” temperature initiators are used during and/or after inversion. The use of such “low” temperature initiators improves polymerization rates and grafting values, while reducing the swell index and the amount of rubber used, thereby producing improved HIPS more rapidly and at a lower cost. Also disclosed are HIPS compositions and products produced by such “low” temperature initiators as well as a method of producing improved HIPS.

    Abstract: An optical resin, of which the refractive index continuously changes in a specific direction, is produced by filling a polymerization container with a mixed solution containing at least one type of polymerizable monomer or polymerizable monomer sol and at least one type of substance whose solubility parameter differs by 7 (cal/cm.sup.3).sup.1/2 or less and refractive index by 0.001 or more from those of a polymer produced by polymerization of the monomer, and by subjecting the mixture to polymerization reaction by applying heat or energy rays to the container from outside so that the polymerization reaction starts and progresses preferentially from a particular region of the mixture, thus forming a concentration gradient of the substance having different refractive index.The polymerization container may be made of a polymer which swells and dissolves into the mixed solution from an inner wall thereof. After completing the polymerization reaction, the optical resin is subjected to hot drawing to obtain an optical conductor. Further, post-treatment based on crosslinking reaction is applied to improve heat resistance.

    Abstract: A process for the manufacture of materials with a high chemical and mechanical resistance in which for each 100 parts by volume of vinylester resin treated with 0.85-1.47 parts by volume of an accelerant in the form of cobalt naphthenate, there are added at least in two batches 50-900 parts by volume of an inorganic filler constituting previously roasted at a temperature not lower than 470 K disintegrated to a particle size of at least 30 .mu.m phosphogypsum or a composition of phosphogypsum with glass-forming oxides or phosphogypsum with magnetite or phosphogypsum with microsphere, after which on continuous stirring there is added, if necessary, up to 60 parts by volume of styrene and/or up to 0.2 parts by volume of dimethylaniline, and then the whole is polymerized in the presence of know initiators such as organic peroxides. The materials with a high chemical and mechanical resistance constitute polymerized composition of synthetic resin and inorganic fillers, consisting of 7.5-88.1% by weight of vinylester resin, styrene and/or a low-molecular-weight unsaturated polyester resin in a quantity up to 34.1% by weight, and 14.3-86.6% by weight of phosphogypsum or 0.4-46.6% by weight of phosphogypsum and 6.4-44.8% by weight of glass-forming oxides or 4.6-53.5% by weight of microsphere or 5.5-42.1% by weight of magnetite. The process for the manufacture of these materials makes it possible to utilize industrial wastes resulted from production of phosphoric acid, while the material itself in all its varieties is characterized by a very good resistance to aggressive media, also at elevated temperatures, and suitable for processing by mechanical methods as well as for combining with other materials by using to that end an incompletely polymerized composition of the material.
