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
The gas permeability of 0, and N, for homogeneous and composite membranes prepared from poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) samples with different molecular weight parameters was investigated. Temperature dependencies of gas permeability coefficients and permselectivity were determined for
