Document Type and Number:
WIPO Patent Application WO/2016/042492
Kind Code:
A3
Abstract:
Copolymers of PEEK and PEEK/PEK and methods of preparation thereof are provided. The melt temperatures of the PEEK copolymer and PEEK/PEK copolymer compositions are in the range of 350 °C to 420 °C. The compositions are based on PEEK monomers biphenol and 4,4'-difluorobenzophenone with other PEEK co-monomers such as hydroquinone and PEK co-monomers such as 4-chloro-4'- hydroxybenzophenone, 4,4'-difluorobenzophenone and 4,4'-dihydroxybenzophenone.
