Extrudable polycarbonate molding compositions |
摘要 |
A thermoplastic molding composition comprising A) at least one member selected from the group consisting of polycarbonate and polyestercarbonate and B) a phosphorus compound is disclosed. The composition wherein A) is a mixture of (A.1) 99.9 to 40 wt. % of branched member, and (A.2) 0.1 to 60 wt. % of linear member, is characterized by high melt stability and improved mechanical properties, particularly improved stress crack resistance under the effect of chemicals and a higher notched impact resistance. The composition is especially suitable for producing profiles, films or sheets of any type in an extrusion process.
