Abstract: Prodn. comprises conversion of liq. crystal forming monomers in presence of resin and aromatic hydrocarbon during the conversion. Aromatic hydrocarbon is pref. (i) a 7-12C alkylbenzene; (ii) a 1-3 halogen-substd. benzene; or (iii) a partially or wholly- hydrogenated naphthalene-, biphenyl- or terphenyl-deriv.. The use of mesitylene and of p-xylene is exemplified. ADVANTAGE - Improved c.f. prior-art processes (e.g. DE3505142) where relatively large amts. of solvents were used with consequent low space-time yields and difficulties in prod. isolation

Abstract: The use of polyarylene-ether-sulphones and polyarylene-ether-ketones or mixts. thereof (I) for encapsulating electrical and electronic components is claimed. (I) are polyarylene-ether-sulphones with repeating units of formula -(Phe-CMe2-Phe-O-Phe-SO2-Phe-O)- (IIA) and/or -(Phe-SO2-Phe-O)- (IIB) (with Phe = 1,4-phenylene). ADVANTAGE - (I) are processed more easily and cheaply than thermosetting resins and ceramics, more suitable than PET and PBT for encapsulating components which are exposed to high thermal loads, and cheaper and more universally applicable than LC polymers. (I) are esp. suitable for prodn. of printed circuits by the SMD technique.

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
