Title:
STABILIZATION OF POLYMERIC STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2011/119392
Kind Code:
A3
Abstract:
A method for stabilizing a polymeric structure against thermo-oxidative degradation is described. A polymeric core structure is provided with a skin layer that contains a skin resin in which the skin resin at least partially envelops a portion of the core structure. The skin structure then provides a barrier that thereby stabilizes the portion of the structure that is enveloped. The skin resin is made from a treated polyarylene sulfide.
