    Abstract: Fire-resistant vinyl ester-urethane resins (I) are claimed, contg. 2-20 wt.% (w.r.t. resin) of a phosphate ester of formula (II); R1, R2, R3 = aliphatic or aromatic gp. (same or different). The resin contains gps. of formula (a) CH2=CR-COO-, (b) -CO-NH-R'-NH-CO-, opt. (c) -O-R"-O- and opt. (d) -NH-R"'-NH-, pref. all 4 gps. (a-d) (with R = H or Me; R', R" and R"' = divalent aliphatic, cycloaliphatic or aromatic gps. with 4-40, 2-500 and 2-100 C atoms respectively; pref. R' = 6-20C arylene and R" = 4-100C aliphatic gp.). USE/ADVANTAGE - (I) are useful esp. for the prodn. of fibre-reinforced composites with high temp. resistance, esp. for structural components in vehicles and buildings; these resins are effectively fireproofed by addn. of (II).

    Abstract: The use of curable dough moulding compounds (BMC) (I) for the prodn. of directly metallisable headlamp reflectors is claimed. In addition to (A) unsatd. polyester (UP) resins, (C) low-shrinkage polymer components, (D) reinforcing glass fibres, (E) fillers, (F) peroxide initiators and opt. (G) other additives, these materials also contain (B) 2-12 wt.% crystalline unsatd. polyester which is insol. in styrene at room temp. Also claimed are headlamp reflectors made from (I). Pref. compsn. (I) contains 8-20 wt.% (A) in the form of a soln. in styrene, 2-12 wt.% (B), 5-12 wt.% (C), 8-20 wt.% (D), 40-70 wt.% (E), 0.1-1 wt.% (F) and opt. (G) (to make up 100 wt.%). (B) is a condensation prod. of fumaric acid, opt. together with terephthalic acid, with butane-1,4-diol. (C) is PMMA or a satd. polyester.
