Xenoy® and Noryl® GTX Engineering Thermoplastics Blends

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 Juliano of GE Corporate Research Laboratories presented a comprehensive review at the last IUPAC Meeting of The Hague(1) where he showed how the evolution of science and technology of blends (2,3) based on polyphenylene oxide, bisphenol A polycarbonate, polybutylene teraphthalate, polyamides and polyacetals, created many more opportunities for the development of engineering thermoplastics with attractive combination of attributes.
