Polymeric material

A method of making a composite material, the method comprising:

• (i) selecting a polymeric materials having a MV in the range 0.07 to 0.11 KNsm−2 when measured at a shear rate of 1000 s−1, wherein said polymeric material has a moiety of formula
• and/or a moiety of formula
• wherein m,r,s and w independently represent zero or a positive integer, E and E′ independently represent an oxygen atom or a direct link, G represents an oxygen atom, a direct link or a —O-Ph-O— moiety where Ph represents a phenyl group and Ar is selected from one of the following moieties (i) to (vi) which is bonded via one or more of its phenyl moieties to adjacent moieties
• (ii) contacting said polymeric material with a filler means to prepare said composite material.
