Definitions
- EKS block copolymer from the monomers terephthaloyl chloride (TPC) , 4 , 4' - diphenoxybenzophenone (DPB) , and 4, 4' -bis(4- phenylphenoxy)diphenyl sulphone (BPS)
- TPC terephthaloyl chloride
- DPB diphenoxybenzophenone
- BPS 4' -bis(4- phenylphenoxy)diphenyl sulphone
- a block length of 4 indicates 4 repeat units, for example (DPB-TPC) repeat units in a block of structure DPB-TPC-DPB-TPC-DPB-TPC-DPB-TPC-DPB.
- the copolymers may also be prepared by a process wherein the EKS units are formed separately as blocks by polymerisation of appropriate monomers, and the EK blocks are subsequently formed by polymerisation of appropriate monomers together with the already-formed EKS blocks.
- block lengths of up to 12, preferably not more than 10.5, are preferred as aforesaid. It will be appreciated that in both of these processes, the block length formed by the subsequent polymerisation step will be determined by that of the pre-formed EK or EKS block and by the relative proportions of EK to EKS, and the second block will form automatically because the EK comonomer has already reacted to form the EK blocks.
- Solvent dichloromethane of which 50 ml was added at the start, with a further 20 ml used to wash in the reactants.

Abstract
Blocs de copolymères polyéthercétone/sulfone, dans lesquels les blocs de polyéthercétone ont une dimension suffisante pour rendre le copolymère partiellement cristallin avec des teneurs en sulfone supérieures à 40 %, ce qui produit normalement une structure amorphe pour les copolymères désordonnés.
