Abstract

Volume flow of epoxide prepolymers and the effect of compression rate, temperature, and molecular weight on it are described. An increase in longitudinal volume viscosity with decreasing volume deformation, increasing compression rate, and increasing temperature has been observed. The molecular weight seems to have no influence.
