摘要：
Rigid polyurethane foams that can be produced at component volumes ratios of less than 4:1 are prepared from an isocyanate component that contains certain polyfunctional (meth)acrylate compounds. These isocyanate components are mixed with a polyol component to produce rigid foams. The foams are particularly suitable for foam-in-place applications, such as for reinforcing structural members of automobiles.
