Abstract
Polymer composition (C) comprising a poly(aryl ether ketone) (P1) chosen from polyetheretherketones, polyetherketoneketones and polyetheretherketone-polyetherketoneketone copolymers, a polyphenylsulfone (P2), and a reinforcing fiber (F), with the exception of a polymer composition consisting of 90 wt %, based on the total weight of the polymer composition, of a polymer blend consisting of 85 parts by weight of a polyphenylsulfone and 15 parts by weight of a polyetheretherketone, and 10 wt %, based on the total weight of the polymer composition, of glass fiber.
Claims22
A polymer composition (C) comprising
- a poly(aryl ether ketone) (P1), of which more than 50 wt % of the recurring units are recurring units of the formula:
- a polyphenylsulfone (P2) of which more than 50 wt % of the recurring units are recurring units of the formula:
- and
- a reinforcing fiber (F), wherein
- the weight of the poly(aryl ether ketone) (P1), based on the total weight of the poly (aryl ether ketone) (P1) and the polyphenylsulfone (P2), is above 30% and below 80%, and
- the reinforcing fiber (F) comprises either a glass fiber, present in an amount of the range 25 to 48 wt % based on the weight of the polymer composition (C), or a carbon fiber, present in an amount of the range 12 to 40% based on the weight of the polymer composition (C).
A polymer composition (C) comprising
- a poly(aryl ether ketone) (P1), which is a polyetheretherketone of which essentially all the recurring units are recurring units of the formula
- a polyphenylsulfone (P2) of which essentially all the recurring units are recurring units of the formula
- and
- above 12 and below 40 wt %, based on the weight of the polymer composition (C), of a reinforcing fiber (F) which is a carbon fiber, wherein
- the weight of the poly (aryl ether ketone) (P1), based on the total weight of the poly(aryl ether ketone) (P1) and the polyphenylsulfone (P2), is above 30% and below 80%.
A polymer composition (C) comprising
- a poly(aryl ether ketone) (P1), which is a polyetheretherketone of which essentially all the recurring units are recurring units of the formula
- a polyphenylsulfone (P2) of which essentially all the recurring units are recurring units of the formula
- and
- above 25 and below 48 wt %, based on the weight of the polymer composition (C), of a reinforcing fiber (F) which is glass fiber, wherein
- the weight of the poly (aryl ether ketone) (P1), based on the total weight of the poly(aryl ether ketone) (P1) and the polyphenylsulfone (P2), is above 30% and below 80%.
