Claims
- 1. A molded foam article produced by a process comprising reacting (1) an organic polyisocyanate; (2) at least one compound containing a plurality of isocyanate-reactive groups; and (3) an internal mold release system comprising (a) a carboxylic acid and (b) a compound selected from the group consisting of a fatty polyester, a fatty acid ester and a fatty amide.
- 2. A process as in claim 1, wherein said carboxylic acid is selected from the group consisting of polymerized oleic acid, oleic acid, adipic acid, lauric acid, stearic acid, hydroxystearic acid, terephthalic acid, behenic acid, arachidonic acid, linoleic acid, linolenic acid, ricinoleic acid and mixtures thereof.
- 3. A process as in claim 1 wherein said fatty polyester is a mixed ester comprising the reaction product of (a) a monofunctional monomer; (b) a difunctional monomer; and (c) a polyfunctional monomer.
- 4. A process as in claim 3, herein said fatty polyester is a mixed ester comprising the reaction product of (i) aliphatic dicarboxylic acids; (ii) aliphatic polyols and (iii) monocarboxylic acids comprising 12 to 30 carbon atoms.
- 5. A process as in claim 4, wherein said fatty polyester comprises the reaction product of (1) adipic acid, (ii) pentaerythritol and (iii) oleic acid.
- 6. A process as in claim 1, herein said fatty acid ester is selected from the group consisting of buryl stearate, tridecyl stearate, glycerol trioleate, isocetyl stearate, ditredecyl adipate, stearyl stearate, glycerol tri-(12-hydroxy) stearate, dioctyl dimerate, ethylene glycol distearate.
- 7. A process as in claim 1 wherein said fatty amide is selected from group consisting of oleamide, stearamide, stearyl stearamide, N-2-hydroxyethyl (12-hydroxy)stearamide and erucyl erucamide.
