Abstract
The present disclosure relates to articles formed from composition comprising a melt polycarbonate component and an interfacial polycarbonate component. The resulting articles exhibit mechanical properties improving upon articles formed from polycarbonate prepared according to conventional melt polymerization processes.
Claims20
An article formed from a composition consisting of:
- a melt polycarbonate resin derived from diphenyl carbonate and having a Fries content of less than about 800 ppm;
- and
- an interfacial polycarbonate resin mixed with the melt polycarbonate resin,
- wherein the composition exhibits a melt volume rate of between about 20 cm3/10 minutes and about 30 cm3/10 minutes at 1.2 kg and 300° C., and
- wherein the article formed from the composition exhibits an IZOD Notched Impact performance that is greater than an IZOD Notched Impact performance of an article formed from a comparator composition consisting essentially of the melt polycarbonate resin within the ductile to brittle transition temperature range of the composition and the comparator composition.
