Abstract

Cellular materials are obtained by interacting an unsaturated polyester with at least 2 isocyanate-reactive groups per molecule, an ethylenically unsaturated comonomer, an organic polyisocyanate and water in the presence of a polymerization catalyst, a volatile organic liquid which is inert with respect to the other ingredients, and a thermoplastic film-forming polymer. The majority of isocyanate-reactive groups may be hydroxyl. Unsaturated polyesters specified are made from a : b -unsaturated polycarboxylic acids, with or without the addition of saturated or aromatic mono- or poly-carboxylic acids, and polyhydric alcohols. Among the acids mentioned are trimesic and trimellitic acids. Polyhydric alcohols part from the usual glycols include diethylene glycol, trimethylol propane, trimethylol ethane, pentaerythritol and glycerol. The proportions of the acids and polyols are so chosen to give the required 2 or more isocyanate-reactive groups which are usually hydroxyl groups. Specified comonomers include styrene and derivatives thereof, esters and nitriles of acrylic and methacrylic acids, vinyl and vinylidene halides, and esters of vinyl and allyl alcohols including diallyl phthalate. Polyisocyanates specified, include, apart from the usual di-isocyanates, tri-isocyanates such as 2:4:6-triisocyanatotoluene, 2:4:41 - triisocyanato - diphenylether, and the reaction product of an excess of di-isocyanate with trimethylol propane, and the uretedione dimers and isocyanurate polymers of di-isocyanates. Specified polymerization catalysts include benzoyl peroxide, methyl-ethylketone peroxide, cumene hydroperoxide, cyclohexanone peroxide, and cobalt naphthenate. Volatile liquids are preferably soluble in the reaction mixture and boil at temperatures not exceeding 90 DEG C., and preferably below 50 DEG C., examples being various fluorine and chlorine containing hydrocarbons, pentanes and hexanes, acetone and di-isopropyl ether. Thermoplastic film-forming polymers include cellulose ethers and esters, polymers and co-polymers of vinyl chloride and vinyl acetate (partially hydrolysed). Catalysts for the isocyanate reaction include various nitrogen containing bases, potassium carbonate, acetate and naphthenate, various lead zinc and tin compounds. Various silicone and polyether surfactants are mentioned. Preferred compositions include, on the weight of the total mixture: 15-40% polyisocyanate, 0.25-4% polymerization catalyst, 5-20% volatile liquid, 0.5-3.0% water, and 2-10% thermoplastic film-forming polymer.
