| abstract | A crystalline polyarylether capable of being shaped into fibres or films or moulded or used as a matrix in composites, contains repeating units Ph'n, Ar<1> and Ar<2> connected by ether linkages, wherein Ph' is 1, 3 or 1, 4- phenylene optionally substituted with 0 to 4 methyl or chloro groups. n is an integer from 1 to 4 Ar<1> is Ph [CO [Ph' CO]x Ph] y wherein x = 0 or 1 y = 1 or 2 Ph is 1,4-phenylene optionally substituted with 0 to 4 methyl or chloro groups, and Ar<2> is [Phn SO2 ]v Ph'w wherein u, v and w are integers from 1 to 4; said units being in the relative molar proportions: Ph'n 40 to 60% Ar<1> 92 to 50% of the total of Ar1 and Ar<2>. Ar<2> 8 to 48% of the total. |
