Abstract
Procedure for obtaining thermoplastic molding materials with improved fluidity from styrene polymerizates and 10 to 60% by weight of a fibrous reinforcing agent, characterized in that firstly styrene is polymerized at temperatures in the area between 200 to 4OOºC, thermally, or at temperatures in the range of 150 to 250ºC in the presence of radical initiators, with styrene oligomers being formed with a molecular weight average of 400 to 1,800, these styrene oligomers, if appropriate, are hydrogenated and then incorporated into the styrene polymers in amounts of from 0.05 to 1.8% by weight.
