Abstract: Thermosetting resin compositions containing vinyl ester resins having terminal unsaturation, vinyl aromatic monomers, and dicyclopentadiene alkenoate concentrates are useful to make fibrous reinforcement laminates. The use of the dicyclopentadiene alkenoate concentrate accelerates the rate at which hardness develops during room temperature cure.

Abstract: Superior frictional materials are formed by heating under pressure in the presence of a filler, e.g., asbestos, and a source of formaldehyde, e.g., hexamethylenetetramine, the polymers formed by reacting (1) a mixture of compounds selected from the group having the formulaR.sub.1 --A--CH.sub.2 --OCH.sub.2 --.sub.y A--.sub.x CH.sub.2 --OCH.sub.2 --.sub.y R.sub.3wherein each A is an independently selected aromatic radical having the formula ##STR1## WHEREIN EACH R.sub.1 represents an independently selected radical from the group consisting of hydrogen, --CH.sub.2 --OCH.sub.2 --.sub.y R.sub.3 ; each R.sub.2 represents an independently selected radical selected from the group consisting of R.sub.1, halogen or an alkyl group of 1 to 10 carbon atoms; R.sub.
