with molecular terminals blocked with an aromatic group containing an aromatic hydrocarbon with an aromatic polyamine having steric hindrance at up to 100°C. The method can be used to cure polycarbodiimides at lower temperatures (of up to lOOC), giving cured copolymers with a surface pencil hardness of at least H. JO7278403 Thermoplastic resin alloy for vehicle components Mitsui DuPont Polychemical KK Priority date 11 April 1994; publication date 24 October 1995 A thermoplastic resin comprising ABS and polycarbonate with a modified ethylene-CO(meth)acrylate copolymer, graft-modified with an acid or anhydride, has high impact strength and good mouldability. It retains high resistance to heat and mechanical strength and can be used for automotive components, electrical or electronic parts and building products. 508109365 Near infrared absorber, with high resistance to heat Nippon Seishi KK Priority date 13 October 1994; publication date 30 April 1996 A near infrared absorber composition contains a bisthiourea compound and a copper compound. It can be added to resins or coated onto various materials to impart near infrared absorbing properties, with good resistance to heat. Variations can also be used as an absorbing material for heat rays. US5464903 PVC compound plasticized with an ethylene copolymer E I DuPont de Nemours & Co Priority date 31 October 1994; publication date 7 November 1995 A plasticized PVC compound can be prepared with a miscible amount of an ethylene copolymer with a melt index of 1 to 100, selected from ethylene/vinyl acetate bipolymers, ethylene/vinyl acetate/CO, terpolymers and ethylene/l -8C alkyl acrylate/CO,

terpolymers and, optionally, a secondary non-ethylene plasticizer. Prior to meltcompounding some of the primary plasticizer can be substituted with a modifier comprising a cross-linked ethylene copolymer and a low molecular weight nonethylene copolymer plasticizer. The process reduces gel or unfluxed PVC and allows use of a wider range of plasticizers, processing conditions and equipment SU1646278 Fire-resistant PVC compound N I Golovnenko Priority date 26 December 1988; publication date 10 November 1995 A tire-resistant PVC compound contains: suspension PVC, complex ether plasticizer, lead stabilizer, calcium stearate, antipyranantimony trioxide, zinc oxide, boric acid and aluminium oxide trihydrate. It is prepared in two stages, with premixing the main components at 60°C for S- 10 minutes and then adding a heated suspension of the remaining components and continuing the mixing at a higher temperature. The fire-resistant compound has reduced emission smoke (by a factor of 1.6) and separation of hydrogen chloride in combustion is lo-20% lower. Relative elongation after thermal ageing is increased by 25%. The compound can be used for shells or casings of electrical conductors and cables, and for coverings under increased fire hazard. JO72772248 Polyester film for audio tape with good durability and reel-up properties Teijin Ltd Priority date 30 March 1994; publication date 20 October 1995 A polyester film for audio magnetic tape includes inert organic particles of an average grain size of 0.5-3.0 urn and inert inorganic particles of an average 0.1-3 .O urn grain size. The Young’s modulus in the longitudinal direction is 600-l 500 kg/mm2, the friction coefficient (M) is 0.4-0.7 when the pad running passes 50 and the variation of
