Embodiment

[0097] The following examples are intended to further describe the present invention in detail, but should by no means be construed as limiting the scope of the present invention. It should also be understood that the formulation amount (% by mass) of the fluorine-containing resin is based on the total amount of the combined fluorine-containing resin and low-temperature decomposable engineering plastics.

Synthetic example -1

[0099] Synthesis of Fluorine Resin

[0100] Put 200L of pure water into an 820L glass-lined autoclave, and then vacuumize after bubbling thoroughly with nitrogen. Charge 113 kg 1-fluoro-1,1-dichloroethane, 95 kg hexafluoropropene (HFP) and 85 kg cyclohexane, charge 292 g perfluoro(1,1,5-trihydro-1-pentane ene) (HF-Pe), and the system was maintained at 35° C. and a stirring speed of 200 rpm. After that, load tetrafluoroethylene (TFE) until it reaches 0.71MPaG (7.25kg / cm 2 G), then charge ethylene until it reaches 0.78MPaG (8kg / cm 2 G).

[0101] A solution of di-n-propylperoxydicarbonate in methanol (50%, 1.9 kg) was charged to initiate polymerization. A mixed gas of TFE:ethylene (Et):HFP (39.2:43.6:17.3 mole%) was continuously supplied to the system so as to keep the inner pressure of the autoclave at 0.78 MPaG. Stirring was continued for 32 hours while continuing to supplement perfluoro(1,1,5-trihydro-1-pentene). The system pressure was returned to atmospheric pressure, ...

Embodiment 1

[0109] The fluorine-containing resin obtained by Synthesis Example-1 is formulated with polyacetal (product name: Derlin 150SA, produced by E.I.du Pont de Nemours and Company) in a ratio of 0.25% by mass, and these materials are blended in polyethylene bags, And using an extrusion film molding machine (type: single shaft; screw size: 30mm, LD: 25; round rod die: 30mm, L330mm; manufactured by Rikua) at a screw rotation speed of 6-7rpm and an extrusion temperature of 200°C molded. Extrusion torque, extrusion pressure and extrusion speed are shown in Table 1.

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 DEG C. and a decomposition temperature of not higher than 300 DEG 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.
