    Abstract: The invention concerns flame-resistant thermoplastic moulding compounds containing: A) between 1 and 97 wt % of at least one polycarbonate, polyamide, polyester, polyolefin or polymethacrylate or a mixture of the above-mentioned thermoplastic polymers; B) between 1 and 97 wt % of at least one graft polymer consisting of: b1) between 40 and 80 wt % of a graft basis comprising a rubber-elastic polymer with a glass transition temperature of less than 0 DEG C; and b2) between 20 and 60 wt % of a graft overlay comprising: b21) between 50 and 95 wt % vinylaromatic monomers of general formula PHI , in which R designates a C1-C8 alkyl group or a hydrogen atom and R designates a C1-C8 alkyl group, and n has the value 0, 1, 2 or 3 or methylmethacrylate or mixtures thereof; and b22) between 5 and 50 wt % acrylonitrile, methacrylonitrile, methylmethacrylate, maleic acid anhydride or mixtures thereof; C) between 1 and 97 wt % of at least one thermoplastic copolymer comprising: c1) between 50 and 95 wt % vinylaromatic monomers of general formula PHI or methylmethacrylate or mixtures thereof; and c2) between 5 and 50 wt % acrylonitrile, methacrylonitrile, methylmethacrylate, maleic acid anhydride or mixtures thereof; D) between 1 and 50 wt % flame retardants containing iminophosphoranes; and E) between 0 and 50 wt % further additives.

    Abstract: The use of copolymers (I) contg. 0.1-99.9 wt% 4-vinylphthalic anhydride, 4-vinyl-phthalic acid and/or dialkyl 4-vinylphthalate ester (II) and 99.9-0.1 wt% vinyl and/or diene comonomer(s) (III) as components of polymer alloys is claimed. ADVANTAGE - (I) have a desirable combination of properties as components of polymer alloys, e.g. markedly better heat distortion temp. than corresp. styrene homopolymers, together with the possibility of reactive phase coupling (via acid or anhydride gps.) (I) are therefore useful as compatibilisers in polymer alloys and for the prodn. of polymeric networks; copolymers contg. more than 50 wt% 4-vinylphthalic acid units are soluble in aq. alkali and are therefore also useful for the prodn. of resist materials. In an example, 4-Vinylphthalic acid was prepd. by bromination of phthalic acid with bromine in aq. NaOH soln., followed by reaction with ethylene for 16 hrs. at 100 deg. C and 40 bar in the presence of Et3N, Pd(OAc)2, tri-o-tolyl-phosphine and DMF, pptn. with CaCl2, soln. and acidifcation. The acid obtd. was sublimed at 90 deg. C and 0.03 mbar to give 4-vinylphthalic anhydride (VPA). A copolymer contg. 10.5 wt% VPA and 89.5 wt% styrene (by FT-IR analysis) was prepd. by radical polymerisation in acetonitrile with AIBN as initiator, followed by re-pptn. from THF/methanol. The prod. had Mn, 5700; Tg, 91 deg. C (cf. 4900, 74 deg. C for 100% styrene homopolymer); a copolymer of 67.4 wt% VPA and 32.6 wt% styrene was soluble in aq. NaOH soln., with Mn = 2200 and Tg = 160 deg. C.

    Polyphenylene ether] polyamide materials with ductile fracture properties at low temp. - contain thermoplastic polyamide, polyphenylene ether, and diene-vinyl]-aromatic block copolymer with specified shore hardness

    Abstract: Impact resistant thermoplastic moulding materials (I) contain (A) 15-75 wt.% thermoplastic polyamide, (B) 20-70 wt.% polyphenylene ether (PPE), (C) 5-15 wt.% conjugated diene/vinylaromatic block copolymer with Shore hardness above 80A and (D) 0-60 wt.% other additives. Pref. (I) contains 35-54 wt.% (A), 38-50 wt.% (B) and 8-15 wt.% (C). (C) comprises at least 2 vinyl-aromatic polymer blocks (A, A') and at least 1 diene polymer block (B, B'), pref. with formula A-B-A'-B'. (B) is dispersed in (A) with mean particle dia. below 0.8 micron, and pref. consists of PPE with mol. wt. 40,000-55,000 and acid number of 1.8-3.2, derived from (b1) 70-99.95 wt.% PPE, (b2) 0-25 wt.% vinyl-aromatic polymer and (b3) 0.05-5 wt.% cpd(s). with double or triple bond(s) and functional gp(s)., i.e. carboxylic acid, ester, amide or anhydride, epoxide, oxazoline or urethane. USE/ADVANTAGE - Useful for the prodn. of fibres, film and moulded prods. Also claimed are moulded prods. obtd. from (I). (I) have (esp.) good notched impact strength and impact penetration resistance combined with ductile properties at low temp., and are useful esp. for injection moulded or extruded parts which are subjected to thermal stress in automobile
