The present invention is directed to a process for producing a molded product comprising n (A) reacting: n (i) an organic polyisocyanate having an isocyanate group content of from 5 to 45% by weight, preferably from 15 to 35% by weight, and most preferably from 20 to 35% by weight, prepared by reacting: n (a) an organic di- and/or polyisocyanate, and n (b) an active hydrogen containing fatty acid ester prepared by reacting an alcohol or polyol with an aliphatic, saturated or unsaturated fatty acid, said ester being characterized in that at least one aliphatic acid which contains more than 8 carbon atoms is built into the molecule, said ester further characterized as having an acid number of from 0 to 100 and a hydroxyl number of from 0 to 150 with at least one of said numbers being greater than zero, said ester having an average molecular weight of from 500 to 5000, n (ii) an isocyanate reactive component comprising: n (a) from about 0.5 to about 10% by weight based on the weight of components (ii)(b) and (ii)(c), of a zinc carboxylate containing from 8 to 24 carbon atoms per carboxylate group, n (b) from about 0.3 to 100% by weight, preferably from 0.5 to 95% by weight, more preferably from 5 to 45% by weight, and most preferably from 10 to 35% by weight, based on the weight of components (ii)(b) and (ii)(c), of a compatibilizer which compatibilizes said carboxylate in component (ii), and n (c) 0 to about 99.5% by weight, preferably from 5 to 99.5% by weight, more preferably from 55 to 95% by weight, and most preferably from 65 to 90% by weight, based on the weight of components (ii)(b), and (ii)(c), of at least one active hydrogen containing compound other than said compatibilizer, n at an isocyanate index of from about 90 to about 400 and preferably from about 95 to about 115, in a closed mold, n (B) allowing the components to react, and n (C) removing the product from the mold. |
