Abstract

1406610 Shaped polyurethane/polyester articles IMPERIAL CHEMICAL INDUSTRIES Ltd 27 Nov 1972 [10 Dec 1971] 57478/71 Headings C3P and C3R [Also in Division B5] A shaped article of a polymeric material, which article is capable of being further shaped, is produced by charging to a moving support surface a fluid mixture of precursors of the polymeric material comprising (a) from 5% to 95% by weight of the precursors of a polyurethane comprising at least one polyfunctional compound containing at least two groups reactive with isocyanate groups and at least one polyisocyanate, and (b) from 95% to 5% by weight of the precursors of a cured polyester resin comprising at least one ethylenically unsaturated polyester and at least one ethylenically unsaturated monomer copolymerizable therewith, and causing or allowing the mixture of precursors when in contact with the support surface to react to an extent such as to produce a handlable shaped article which is capable of being further shaped. In the examples mixtures comprising 4 : 41-diphenyl-methane diisocyanate, an unsaturated polyester prepared from propylene glycol, fumaric acid and isophthalic acid, styrene, tertiary butyl peroxide, dibutyl tin dilaurate, oxypropylated bisphenol A, a polyester polyol prepared from adipic acid, glycerol and diethylene glycol, stannous octoate, tertiary butyl perbenzoate, triethylene glycol, hydroquinone, yellow pigment, calcium carbonate, zinc stearate, dropped glass fibre, red pigment and glass fibre mats are reacted on belts to give flexible pliable sheets. The belt may be an endless belt which may be provided with heated platens. The sheets may be formed between polymeric sheets. The flexible, pliable sheets may be cured and moulded.
