Abstract: PURPOSE:To improve stretching properties, gas barrier properties, and resistance to hot water, oil and impact by mixing a specified ethylene-vinyl alcohol copolymer with a specific aliph. copolyamide. CONSTITUTION:A polyamide having an m.p. of 120-200 deg.C and obtd. by copolymerizing 25-80wt.% caproamide with 75-20wt.% at least two aliph. polyamides at random is allowed to react with an agent for modifying terminal group contents (e.g. acetic acid) to give an aliph. copolyamide having a relative viscosity (JIS K6810, in 98% sulfuric acid, in 1% concn., and at 25 deg.C) of 1.7-4.0 and contents of terminal carboxyl group [X] and terminal amino group [Y] satisfying the formula (wherein the unit of [X] and [Y] is mol/g-polymer). 40-5wt.% said copolyamide is mixed with 60-95wt.% saponified ethylene-vinyl alcohol copolymer having an ethylene content of 25-60mol% and a degree of saponification of 90mol% or higher.

Abstract: PURPOSE:To obtain a thermoplastic resin composition excellent in impact resistance, moldability and chemical resistance by adding a small amount of a phosphorus compound to a resin composition comprising an ABS resin, a polyamide resin and a modified vinyl polymer. CONSTITUTION:0.01-1 pt.wt. phosphorus compound (e.g., phosphoric acid, sodium phosphite or triisodecyl phosphite) is added to 100 pts.wt. resin composition comprising 5-95wt.% ABS resin, 5-95wt.% polyamide resin and 1-70wt.% modified vinyl polymer comprising an aromatic vinyl, a vinyl cyanide and an alpha,beta-unsaturated carboxylic acid (e.g., styrene/acrylonitrile/methacrylic acid copolymer). A resin composition having moldability and impact resistance equivalent to those of an ABS resin and heat resistance and chemical resistance inherent in the polyamide can be obtained.

Abstract: PURPOSE:To obtain a granular polymer having a large grain diameter, improved productivity and high heat distortion temperature, by coagulating a copolymer latex containing an N-substituted phenylmaleimide at a specific temperature and heating the coagulation reaction system by a specific method. CONSTITUTION:A mixture consisting of (A) 20-80wt% styrene and/or alpha- methylstyrene, (B) 5-40wt% acrylonitrile, (C) 1-45wt% N-substituted phenylmaleimide and (D) 0-40wt% vinyl based monomer copolymerizable therewith is initially emulsion polymerized. The resultant copolymer latex is then coagulated with a coagulating agent, e.g. NaCl, etc., at 20-120 deg.C and the above- mentioned coagulation reaction system is further heated at 130-195 deg.C for 5sec-3hr while vigorously stirring to give ); Nqd is the discharge flow rate number; D is the diameter of the tank (m); d is the agitating blade span (m); n is the number of revolutions (r.p.s)]. The formed copolymer powder is then separated and recovered.
