In this article, the chemical modification of poly(2,6-dimethyl-l,4-phenylene oxide) (PPO) was carried out by incorporating a n amine group into the PPO backbone. A maximum monosubstitution degree of 65 mol % was reached. The effects of reaction conditions on the functional group content in PPO is d

## Abstract As a first stage in the synthesis of a new class of thermoplastic elastomers, a suitable synthetic route for elastomeric tailorβmade diblock copolymers based on poly(2,6βdimethylβ1,4βphenylene oxide), PPE, as the thermoplastic block and on 1,4βpolyisoprene, PIP, as the elastomeric block
Poly(2,6-dimethyl-1,4 -phenylene oxide) (PPO) is a chemically resistant polymer and, therefore, an attractive material for the formation of membranes. However, membranes of unmodified PPO prepared by an immersion precipitation possess very low hydraulic permeabilities at the filtration processes. T
