Abstract

Wood used for parts of musical instruments is at least partly impregnated with organic polymer. Various liquid unsatd. polymerisable organic cpds. may be used, pref. contg. at least 10wt.% acrylonitrile and 0.01-2wt.-% hardener. Cure can be carried out below 140 degrees C or using ionising radiation. This "polymer wood" has better hardness, compressive and flexural strength than natural woods. Reduced moisture absorption under varying humidity conditions improves dimensional stability and hence functional properties.
