    Abstract: A bulk polymerization reactor takes the form of a vertical, cylindrical vat of a jacket construction defining a reaction chamber which a rotary drive shaft having an offcenter longitudinal section with perforated discs and shearing blades extends vertically through. Successful preclusion of abnormal stagnation of the liquid phase in the reaction chamber during polymerization avoids undesirable colouring in the product whilst assuring stable polymerization and high yield.

    Abstract: 1301166 Graft polymerization process TORAY INDUSTRIES Inc 8 Oct 1970 47811/70 Heading C3G An impact resistant resin is produced by mixing 100 parts by weight of diene rubber particles having a gel content of at least 50% in a latex with more than 10 parts by weight of a monomer composition comprising more than 20% by weight of an aromatic monomer, extracting the diene rubber particles and monomer composition and removing the aqueous phase and bulk polymerizing the extract. The aromatic monomer, e.g. styrene or a substituted styrene may be copolymerized with (meth)- acrylonitrile or an alkyl (meth)acrylate. A grafted rubber latex may be used together with the diene rubber latex. In the examples, (1) polybutadiene is grafted with (a) styrene and acrylonitrile (b) styrene (c) alpha-methyl styrene and acrylonitrile or (d) styrene, acrylonitrile and methyl methacrylate; (2) a mixture of butadiene-acrylonitrile rubber and polybutadiene grafted with styrene and acrylonitrile is grafted with styrene and acrylonitrile and (3) butadiene-styrene rubber is grafted with styrene.

    Abstract: PURPOSE:A threading device having a simple structure and high threading ratio, equipped with guide rollers attached to both ends of each yarn transfer roller and a threading truck traveling along rails are between them. CONSTITUTION:The rope 9 for pulling a threading truck is hung through the yarn transfer rollers 1a-1e on a given thread handling area by an operator, one end of the rope 9 is linked to a rope winder and the other to the yarn linking bar 6 of the threading truck 5. A great number of parallel yarn Y are linked to the yarn linking bar 6, the yarn transfer rollers 1a-1c and the winding rollers 10 are rotated, the wheels 7 and 7' of the threading truck 5 are moved along the rails 4 and 4' and the guides 2 and 2' so that the threading truck 5 is moved along the thread handling area to carry out threading.

    Abstract: PURPOSE:To give the title reactor of improved stability of the polymerization and less abnormal residence of highly viscous materials, with an off-centered shaft of agitator being equipped with blades for scraping the polymer produced and multiporous plates having a specific aperture area ratio. CONSTITUTION:The present invention relates to a bulk polymerization reactor which is equipped, in the reaction vessel A, with such an off-centered shaft of agitator B that the bias of the center of said shaft from the center of the vessel falls within the range of 150% or less of the shaft diameter of the agitator. Said shaft of agitator B carries blades C for scraping polymers attached to the inner wall of the vessel and multiporous plates D with an aperture area ratio of 0.35-0.65, thus providing a novel agitator. When the extent of said bias exceeds 150%, operation of the reactor may become unstable. When the aperture area is 0.65, the temperature distribution and the polymer output could be unstable.
