Abstract
A method of producing rigid or semi-rigid foamed masses comprises reacting together, in the presence of water and a tertiary amine catalyst, an organic diisocyanate and an alkyd resin derived from the reaction of a nondrying oil, a semi-drying oil or a nut oil, an alcohol selected only from polyhydric alcohols containing at least four primary or secondary hydroxyl groups per molecule and a mixture of dicarboxylic acids or their anhydrides, the amount of water being 1 to 5% by weight of the alkyd resin. Oils specified are castor, cottonseed, coconut and palm kernel oils. Pentaerythritol is the preferred polyhydric alcohol. The products can be made self-extinguishing by the inclusion in the reaction mixture of antimony trioxide, chlorinated paraffin waxes or tri-b -chlorethyl phosphate. In examples, resins are prepared by heating respectively: (1) castor oil, (2) crude coconut oil, and (3) cottonseed oil with pentaerythritol in the presence of calcium naphthenate, followed by further reaction with a mixture of adipic and phthalic acids. The products are foamed by mixing with water and a tertiary amine such as N - ethyl - morpholine followed by a mixture of 2 : 4- and 2 : 6-toluylene diisocyanates.ALSO:A method of producing rigid or semi-rigid foamed masses comprises reacting together, in the presence of water and a tertiary amine catalyst, an organic diisocyanate and an alkyd resin derived from the reaction of a non-drying oil, a semi-drying oil or a nut oil, an alcohol selected only from polyhydric alcohols containing at least four primary or secondary hydroxyl groups per molecule and a mixture of dicarboxylic acids or their anhydrides, the amount of water being 1 to 5 % by weight of the alkyd resin.

The products can be made self-extinguishing by the inclusion in the reaction mixture of antimony trioxide, chlorinated paraffin wax or tri-b -chlorethyl phosphate. In examples resins are prepared by heating, respectively, (1) castor oil, (2) colide coconut oil and (3) cottonseed oil with pentaerythritol in the presence of calcium naphthanate, followed by further reaction with a mixture of adipic and phthalic acids. The products are foamed by mixing with water and a tertiary amine such as N-ethyl-morphaline followed by a mixture of 2 : 4- and 2 : 6-toluylene diisocyanates.
