Abstract
Thermoplastic molding compositions containing PA1 (i) polybutylene terephthalate PA1 (ii) a first aromatic polycarbonate resin, and PA1 (iii) a second aromatic polycarbonate resin are disclosed. A high level of Total Light Transmission (herein TLT) is a key characteristic of the compositions of the invention. Preferably, the TLT values of the compositions are higher than those of compositions which contain only said (i) and either (ii) or (iii). Most preferably, the TLT values of the compositions are higher than 80%.
