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
## 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
Dicarboxy-terminated poly(2,6-dimethyl-l ,Cphenylene oxide) (PPO) macromonomers were prepared and subjected to the preparation of tailor-made aromatic thermotropic liquid-crystalline (LC) polyester-graft-PPO copolymers. The macromonomers were obtained by hydrolysis of dimethyl carboxylate-terminated
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
