Title:
METHOD FOR LOWERING THE MELT VISCOSITY OF AN AROMATIC SULFONE POLYMER COMPOSITION, AND METHOD FOR MANUFACTURING AN AIRCRAFT COMPONENT
Document Type and Number:
WIPO Patent Application WO2004081103
Kind Code:
A3
Abstract:
Method for lowering the melt viscosity of an aromatic sulfone polymer composition consisting of at least one aromatic sulfone polymer and, optionally, one or more other ingredients [composition (I)], which comprises using an additive consisting of at least one fluorocarbon polymer comprising recurring units derived from at least one perfluorinated monoolefin and at least one perfluoroalkylvinylether and, optionally, one or more other ingredients [additive (A)]. Method for manufacturing an aircraft component comprising an aromatic sulfone polymer composition consisting of at least one aromatic sulfone polymer and, optionally, one or more other ingredients, which comprises applying to the aromatic sulfone polymer composition the above method for lowering its melt viscosity.
