Abstract
Reaction mixtures, foams prepared from the reaction mixtures, articles containing the foams, and methods of making the foams are provided. The polymeric material in the foam is formed from a polymerizable composition that includes a di(meth)acrylate oligomer and a monomer having a single ethylenically unsaturated group. The foams are highly filled (e.g., at least 60 volume percent of the foam is the filler) and can be thermally conductive. Although the foams contain a large amount of filler, the foams can be compressed at least 40 volume percent with an applied pressure of 50 pounds per square inch (345 kiloPascals).
