Abstract
1,271,061. Self-skinned polymer foams. UPJOHN CO. 5 Jan., 1970 [10 Feb., 1969], No. 463/70. Headings C3C and C3R. Cellular polymer articles having an integrally formed non-cellular skin are formed by moulding a polymer foam forming reaction mixture in a closed mould, of a volume less than that which would be occupied by the resultant foam if the said mixture were allowed to rise freely, a catalyst system being chosen such that the interval between cream time and final rise time of the foam is not more than 33 seconds. Suitable foams may be composed of polyurethanes, polyureas, polyimides, polyamides, polyoxazolidinones and polyisocyanurates. Catalysts capable of providing suitable time intervals may be chosen by trial and error from conventional catalysts, or the required effect may be obtained by using excess quantities of conventional catalysts. Thus, polyurethane catalysts may be employed in amounts varying from 0À1 to 2À0% by weight of the total reactants. Preferred polyurethane catalysts are tertiary amines such as triethylene diamine and dimethylethanolamine, and organic derivatives of tin such as stannous octoate, dibutyl tin dilaurate and dibutyl tin diacetate. Mixtures of such tin and tertiary amine catalysts are particularly preferred. Preferred polyisocyanurate catalysts are tertiary amines such as N,N<SP>1</SP>,N<SP>11</SP>-tris (dialkylaminoalkyl) hexahydrotriazines, N.N-dialkylethanolamines and triethylene diamine in admixture with monomeric homocyclic polyepoxides such as novolac resin glycidyl ethers and glycidyl ethers of non-fused polynuclear phenols. In a preferred aspect of the invention the components of the foam forming reaction mixture are cooled to a temperature of between 0‹ C. to 15‹ C. before being brought together. Examples describe the preparation of integrally skinned rigid foams composed of polyurethanes and polyisocyanurates. Uses.-Upholstery, automobile bodies and padding, furniture construction, walls, partitions and table tops.
