POLYETHER KETONE AND HEATPROOF POLYVINYLCHLORIDE BLEND CONTAINING THE SAME

摘要

PURPOSE: A polyether ketone is provided, which has a high glass transition temperature of more than 160 deg.C and is homogeneously molten and blended with polyvinylchloride within a short period of time even at a relatively low temperature of 180-210 deg.C. And a heatproof polyvinylchloride blend containing the same is also provided, which is applied to a hot water piping pipe. CONSTITUTION: The polyether ketone is formed by performing a self-condensation reaction of 3,5-bis(4-((2,3,4,5,6-pentafluorophenyl)carbonyl)phenoxy)-4-hydroxybenzophenon represented by the formula (1) or 3.5-difluoro-4-hydroxybenzophenone represented by the formula (2) and then substituting 50-80 mol.% of fluorine atoms contained in a molecular structure of the polyether ketone for a polar group. The polyvinyl chloride blend comprises: (i) 10-50 wt.% of the polyether ketone; and (ii) 90-50 wt.% of a polyvinyl chloride.
