Abstract
Disclosed is a composition that includes a liquid prepolymer that is the reaction product of a monoanhydride, a cycloaliphatic epoxy, and an alcohol. Also included in the composition is a maleated polybutadiene that is a reaction product of butadiene, maleic anhydride, and an oxygen scavenger. The composition also includes a tertiary amine accelerator, a free-radical initiator, and a solvent. A prepreg is prepared from the composition by immersing a porous substrate into the composition, drying and curing to the B-stage. A laminate is prepared by forming a stack of prepregs and heating under pressure to the C-stage.
