Abstract: 1337501 Coated pigments BAYER AG 7 Jan 1971 [14 Jan 1970] 782/71 Headings C1N and C1A [Also in Division C3] An inorganic pigment is coated with a non- drying alkyd resin which has been prepared from a polyol containing at least 3 OH groups and having an O : C atomic ratio of not more than 0À7 : 1. The resin may be added in emulsified or dissolved form during final grinding. The pigment is preferably rutile TiO 2 which may be obtained by the sulphate or chloride process and may be coated with Al 2 O 3 or SiO 2 . Iron and chromium oxides are also referred to. Exemplified alkyds are prepared from (1) 1-ethyl hexanoic acid, 1,2,6-hexane triol, phthalic anhydride, malaeic acid; (2) fatty acids obtained in the oxidation of paraffins, trimethylol propane, phthalic anhydride, maleic acid; (3) palmitic acid, 1,3-butane diol, trimethylol propane, phthalic anhydride.

Abstract: New polyurethanes contain units of formula: (where R and R1 are H, 1-6C alkyl, 6-15C aryl, 4-12C where R11 is 1-6C alkyl). The diamines used as chain-extenders are easily available; they break down to biologically acceptable prodts. Casting time of the compsns. is adequate; de-moulding time is short. The compsns. are used to produce moulded goods, e.g., rollers or V-belts, films, textile coatings or polyurethane powders. The foams are used as cushioning, packing and insulation.

Abstract: In the production of moulded articles from unsaturated monomer-free polyesters with a content of polymerization catalysts, the unsaturated polyesters, optionally in the presence of conventional fillers, are prepolymerized to the gel stage by heating, then cooled and the pre-polymers obtained hardened at any later time by reheating while moulding. Conventional peroxide catalysts may be used or 1,2-substituted ethanes of the general formula in which R1 and R3, which may be the same or different, are aromatic radicals, R2 is a hydrogen atom or an aliphatic or aromatic radical, R4 is an aromatic or aliphatic radical, and X and Y, which may be the same or different, signify optionally blocked hydroxyl groups and/or optionally substituted amino groups and/or halogen atoms.
