The preparation of aromatic macromolecular structures by nucleophilic substitution reactions (A), in which polymerization proceeds via the formation of ether linkages, and by the electrophilic substitutions, (B) and (C), where sulfone or ketone linka

Densities, glass transition temperatures and notched impact strengths (NIS) (before and after storing the test samples at 150°C) have been measured for several series of poly(arylene ether sulfone)s. Consideration of these data together with those p

Analysis, mainly by n.m.r. spectroscopy, shows that when copolymers comprising phenylene-ether-phenylene-sulphone and phenylene-ether-phenylene-ether-phenylene-sulphone repeat units are dissolved in 98% sulphuric acid, the ether-phenylene-ether group

Notched impact strength (NIS) has been determined (before and after thermal ageing at 150°C) as a measure of toughness for a wide range of poly(aryl ether sulphone)s and the results correlated with the structure of the polymers' repeat units. It app

Crystalline polyarletherketones of high molecular weight have been prepared previously by polycondensation of aroyl fluorides such as 4-phenoxybenzoyl fluoride in liquid HF, but not by polyether synthesis because these polymers are not soluble in the

Several alkali metal halogenophenylsulphonyl phenoxides have been polymerized in the melt and in solution. Poly(arylene ether sulphones) have also been prepared by polycondensation of 4-halogenophenylsulphonyl compounds with phenols in the presence o

Several 4-halogenophenylsulphonylphenols, useful as intermediates for the synthesis of poly(arylene ether sulphones), have been prepared by partial hydrolysis of the corresponding dihalides and/or by the reaction of 4-halogenoarylsulphonyl chlorides

Measurements of solution viscosity, melt viscosity, and molecular weight by osmometry and by light scattering, made on a series of isomeric poly(phenylene ether sulphones) show that the reduced solution viscosities of these polymers can be taken as a

A study of hydrogen chloride evolution versus time curves for polysulphonylations, conducted in the presence of excesses of sulphonyl chloride groups, shows that chain branching proceeds very much more slowly than chain extension, but that branching
