Abstract
An improved low density resin composition results from curing, in the presence of at least one free radical generator, a resin comprising: PA1 A. polybutadiene containing 50-80% of 1,2 units and having an average moleuclar weight by number lower than 100,000; and PA1 B. inorganic or organic hollow spheres included therein. The resin composition preferably contain a fibrous reinforcing filler, preferably short carbon fibers.
