C08L077/00
US Classification:

525/055000, 264/331140, 525/154000
Abstract:

The present invention is a low-temperature-decomposable engineering plastic resin composition prepared by formulating a low-temperature-decomposable engineering plastic with a fluorine-containing resin, wherein said low-temperature-decomposable engineering plastic has a melting point of not higher than 200 C. and a decomposition temperature of not higher than 300 C., and wherein said fluorine-containing resin is a resin comprising a fluorine-containing polymer, said fluorine-containing polymer having a fluorine atom and at least one atom species selected from the group consisting of hydrogen atom, chlorine atom, bromine atom and iodine atom, said fluorine atom and said at least one atom species being bound to a non-terminal carbon atom constituting a main chain, and said fluorine-containing polymer having substantially no polar functional groups reactive to the low-temperature-decomposable engineering plastic.
