Abstract: PURPOSE:To prepare a high-MW oxymethylene copolymer excellent in heat resistance, etc., in a short time, by preliminarily polymerizing 1,3-dioxolane in the presence of a boron trifluoride polymn. catalyst and bringing the preliminary polymer into contact with trioxane. CONSTITUTION:Preparation is made of a polymn. catalyst selected from coordination compds. of boron trifluoride hydrate and boron trifluoride with an org. compd. contg. an oxygen or sulfur atom. (e.g., boron trifluoride-diethyl ether complex). 1,3-Dioxolane is preliminarily polymerized in the presence of the above-mentioned catalyst to prepare an active poly(oxymethylene/oxyethylene) copolymer (in the form of a soln.) having a number-average MW of 150-20,000, which is then brought into contact with trioxane to prepare an oxymethylene copolymer. This copolymer is suitably used to produce parts of mechanical structures, electrical and electronic components, etc.

Abstract: PURPOSE:To obtain a polyester of a uniform degree of polymerization at a high rate of polymerization, by polymerizing a polyester in a solid state polymerization tank in an inert gas whose dew point is adjusted to a specified temperature. CONSTITUTION:A polyester obtained from a pelletized aromatic dicarboxylic acid and a 2-4C diol (e.g., polybutylene terephthalate) is polymerized for 5-25hr at 170 deg.C to the m.p. -10 deg.C in a solid state polymerization tank in an inert gas (e.g., N2) whose dew point is adjusted to -40 deg.C or below, preferably, -50--70 deg.C.

Abstract: PURPOSE:To obtain a high-MW oxymethylene copolymer inexpensively in high yield within a short time, by premixing a cyclic ether with a polymerization catalyst of a boron trifluoride type, adding the mixture to trioxane and bulk- polymerizing it. CONSTITUTION:A cyclic ether (A) (e.g., propylene oxide or 1,3-dioxolane) is well premixed with a polymerization catalyst (B) selected from among boron trifluoride (hydrate) and a coordination compound of boron trifluoride with an oxygen or sulfur-containing organic compound (e.g., boron trifluoride diethyl etherate). The obtained mixture is added to trioxane, which is bulk-polymerized to give an oxymethylene copolymer. Since the polymerization catalyst can be activated by the cyclic ether, the polymerization time can be shortened and the polymer yield can be improved.

Abstract: PURPOSE:To obtain a thermoplastic resin composition excellent in flexibility, high-temperature properties, compression set resistance, mechanical properties, etc., by mixing a polyamide with a nitrile rubber and a specified organic peroxide and melt-kneading the mixture. CONSTITUTION:The following three components A-C are melt-kneaded together. (A): 5-50pts.wt. polyamide of a m.p. >=170 deg.C; (B): 95-50pts.wt. nitrile rubber; and (C): an organic peroxide having a 1min half-life temperature >=185 deg.C in an amount to provide 0.002-0.05mol of the peroxide group per 100g of the nitrile rubber (B) are melt-kneaded together (the total of A and B being 100pts. wt.). As component A, nylon 11, nylon 12, nylon 6/60 or nylon 6/66/610 is desirable. Examples of component C include di-t-butyl peroxide and 2,5-dimethyl-2,5- di-t-butylperoxyhexyne-3.
