摘要：
A process for making cold-setting, non-shrinkable polyurethane foam resins using a mixture of silicon compounds of the formula:A.sub.x B.sub.x+2whereinx=2-25, preferably 2-5A is the group R' Si O.sub.3/2B is the group (R).sub.3 Si O.sub.1/2R represents an alkyl group having from 1 to 3 carbon atomsR' represents an aryl group having from 6 to 14 carbon atoms, with the proviso that the mixture contains at least one compound wherein x is greater than 3.
