short glass-fibre reinorced polycarbonates

A mixture consisting of

• A) 45 to 97 wt. % of polycarbonate,
• B) 2 to 50 wt. % of short glass fibers, and
• C) 0.1 to 5 wt. % of polyether silicone of the formula (I):
• ##STR7## wherein:
• R.sup.1 signifies an alkyl group having 1 to 30 C atoms, wherein up to 20 wt. % of the alkyl groups can be replaced by phenyl groups and/or aralkyl groups, which groups can be substituted by one or more methyl groups, while the alkyl moieties of the aralkyl groups can contain 1 to 3 carbon atoms,
• A signifies --CH.sub.3 or R.sup.2 -Z-,
• B signifies --CH.sub.3 OR R.sup.2 -Z-,
• R.sup.2 signifies a polyether radical having an average molecular weight of from 200 to 3,000, which is terminated by C.sub.1 -C.sub.6 alkoxy, OH--, ester or carbamate groups,
• Z signifies an alkylene group, which bonds the silicon atom to the group R.sup.2.
• x represents 1 to 20,
• y represents 0 to 50, and
• wherein the average molecule contains a group R.sup.2 -Z- and the ratio of the number of groups R.sup.2 -Z- to the number x amounts to 1:2 to 1:40;
• in each case based on 100 wt. % of A)+B)+C).
