Plasticized polyamide compositions. Kimura, Toshio; Yamada, Keijiro (Toray Industries, Inc., Japan). Japan. Kokai JP 52072753 17 Jun 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L077-00. APPLICATION: JP 75-148439 15 Dec 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Polyamides were plasticized with .epsilon.-caprolactam-amino-terminated polyethylene glycol adipate copolymer (I) or ethylene glycol-polytetramethylene glycol-terephthalic acid copolymer [37353-50-7] impregnated with arom. sulfonamide, glycol, or hydroxybenzoate ester. Thus, 100 parts I pellets were stirred with 400 parts N-butylbenzenesulfonamide (II) [3622-84-2] at 90.degree. for 30 min for complete absorption. Nylon 6 [25038-54-4] (95 parts) melt-blended with 25 parts of the impregnated pellets had plasticizer retention 23.8 phr compared with 18 phr when nylon 6 was blended with II in ratio without I.

Polyester-amide molding compositions

Polyester-amide molding compositions. (Toray Industries, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 58168656 A2 5 Oct 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L077-12; C08K005-10; C08K005-43. APPLICATION: JP 82-51892 30 Mar 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title compns. comprise [A] an aliph. poly(ester amide) consisting of 5-80% ester units (from a C2-6 aliph. diol and a C9-12 aliph.There are some reagents with their cas registry numbers 89436-71-5 and 5153-25-3 are used in this study. dicarboxylic acid) and 20-95% amide units (from a C11-12 aliph. amino acid or lactam or C6-12 aliph. diamine equimol. salt with C9-12 aliph. dicarboxylic acid ) and [B] 1-100% arom. sulfonamide and/or alkyl p-hydroxybenzoate plasticizer. The compns. have excellent impact resistance and are useful as parts for machines, automobiles, and elec. appliances. Thus, 11-aminoundecanoic acid 82.4, 1,4-butanediol 14.3, dodecanedioic acid 20.2, tetra-Bu titanate 0.1, and Irganox 1010 (antioxidant) 0.1 part were mixed to give a poly(ester amide) (I) [85328-14-9] with relative viscosity 1.52, m.p. 155°, ester unit content 25 parts, and amide unit content 75 parts. I pellets (100 parts) and 7.5 parts N-butylbenzenesulfonamide [3622-84-2] were mixed, kneaded, and injected to give moldings with excellent phys. properties. .
