    摘要： Disclosed is a continuous bulk polymerization reactor comprising a cylindrical reaction vessel elongated in the direction of the reacting fluid and a shaft installed within the reaction vessel. A plurality of flow of double helical-ribbon agitators are attached to the shaft in such a way that they face in the same direction, and a plurality of baffles having a relative open area of 5 to 40% based on the cross-sectional area of the internal space of the reaction vessel, are disposed between any adjacent ones of the agitators. Thus the formation of stagnant fluid pockets is avoided and excellent piston flow properties are achieved.

    摘要： Disclosed is a process for continuously producing rubber modified styrene resins wherein the rubbery phase including a rubber-like polymer is transformed into dispersed particles by using a reactor having both a helical-blade agitator mounted in a draft tube and an auxiliary agitator, by establishing a specified agitating force and a specified degree of circulation of the fluid within the reactor, and by maintaining a specified relation between the weight percentages, based on the total amount of all components within the reactor, of the rubber-like polymer and the monomer converted to polymer. According to this process, various grades of high-impact rubber modified styrene resins having excellent surface properties can be obtained without any adhesion of rubber-like matter to the reactor and without any formation of fisheyes in final products.

    摘要： A method of manufacturing rubber modified styrene resins comprising the 1st step of polymerizing a styrene monomer in the presence of a butadiene polymer and an organic peroxide at the ratio of 100 parts by weight, 3 to 15 parts by weight and 0 to 0.01 parts by weight respectively until the polymerization yield of the styrene monomer becomes 2 to 5 time more than the weight of the butadiene polymer, and the 2nd step of polymerizing the full amount of polymer mixture from the 1st step and 0 to 200 parts by weight of the fresh styrene monomer in the presence of 0.01 to 0.9 parts by weight of the organic peroxide until the polymerization yield of the styrene monomer becomes at least 1.5 times more than that of the 1st step. The molded product of the resin thus obtained shows an improved impact strength at the portions wherein polystyrene molecule orientation tends to occur.

    摘要： A process for preparing rubber modified high impact resins by dissolving a rubbery polymer in a monomer containing an aromatic vinyl monomer or a mixture of an aromatic vinyl monomer and a vinyl cyanide monomer followed by polymerizing the monomer, the two steps being carried out in at least two polymerization reactors with a particle disperser placed between the first and second reactors. High impact resins having excellent surface properties are obtained with a savings in a power consumption by controlling:(1) the relationship between the concentration of the polymerized monomer and the content of the rubbery polymer in the first reactor;(2) the relationship between the volume occupied by the polymerizing liquid in the first reactor and the inner volume of the particle disperser; and(3) the peripheral linear velocity of a shearing stirrer in the particle disperser.
