Abstract
The invention pertains to a polymer blend based on PEDEK-PEEK copolymer, which, thanks to the predominance of PEDEK-type units in the copolymer (PEDEK-PEEK), and to the blending with a polyphenylsulfone polymer (PPSU), is effective in delivering superior combination of improved strength and modulus at elevated temperatures and improved ductility, and which is endowed with beneficial partial miscibility behaviour, which is unexpected and advantageous, both for retaining similar high temperature resistance of polymer (PPSU) component, but also for avoiding phase separation and/or reduction in crystallization rate and loss of high temperature performances.
