Polycarbonate-polybutylene teraphthalate

Thanks to their unusual miscibility polymer blends of polyphenylene oxide and polystyrene were the first commercially successful amorphous engineering thermoplastics blends, introduced back, in 1968 Pete Juliauo of GE Corporate Research Laboratories presented a comprehensive review at the last lUPAC Meeting of The Rague(l) where he showed how the evolution of science and technology of blends (2,3) based on polyphenylene oxide, blsphenol A polycarbonate, polybutylene teraphthalate, polyamides and polyacetals, created many more opportunities for the development of engineering thermoplastics with attractive combination of attributes.
