Abstract: Glass-fibre-reinforced styrene polymerisate contg. (A) 10-50 wt. % glass-fibres; (B) 90-3% of a copolymer of styrene with 3-50% of an ethylenically unsatd. mono- or dicarboxylic acid, ester or amide, dicarboxylic acid semi-ester of anhydride, and opt. another comonomer; and (C) 0-87 wt. % of a styrene (co)polymer miscible with (B). The glass fibres are pre-treated with a size in form of a dispersion of soln. contg. an organosilane as adhesion adjuvant and opt. a synth. material as film-former; the organosilane contg. reactive gps. adapted to form a chemical bond with the functional gps. of (B). Used in injection moulding.

Abstract: Asymmetric polyether-polyols having a functionality of from 3 to 8, a hydroxyl number of from 15 to 112 and preferably a compatibility index of less than 50 DEG C are obtained by reacting a) one mol of a polyoxyalkylene glycol having a hydroxyl number of from 15 to 200 with b) from 0.1 to 2 mol of an epoxyalcohol of the formula in which R and R are identical or different and are a hydrogen atom or a -CH2OH radical, x is an integer from 0 to 9 and y is 0 or 1, preferably glycidol, and subsequent c) alkoxylation of the resultant trifunctional to octafunctional intermediate c) in the presence of basic catalysts until the hydroxyl number mentioned has been reached. The asymmetric polyether-polyols are particularly suitable for the production of open-cell polyurethane foams.

Abstract: According to parent patent, a glass-fibre reinforced styrene polymer contains (A) 10-50% glass fibres; (B) 90-3% of a copolymer of styrene with 3-50% of an ethylenically unsatd. nono- or di-carboxylic acid, acid ester or acid amide, a dicarboxylic acid half ester or a dicarboxylic acid anhydride, and opt. other comonomers, and (C) 0-87% of a styrene homo- or copolymer miscible with (B), the glass fibres having been pre-sized with a dispersion or soln. contg. an organosilane as keying agent and opt. a plastic as film-former, the organosilane contg. reactive gps. forming chemical bonds with the functional gps. of (B). In the present improvement, the strength of the reinforced polymer is further increased by using as (B), a graft copolymer of styrene and maleic anhydride onto a styrene polymer.
