PURPOSE:To produce a polymer alloy by uniformly kneading and mixing a different kind of polymers under reduced pressure in a molten state without adding a compatibilizing agent or other specific blend additives. CONSTITUTION:A different kind of polymers are kneaded under reduced pressure of 300Torr or less. Since enthalpy becomes large and molecular motion becomes active, mixing becomes easy and the polymers can be uniformly mixed without using a compatibilizing agent and the damage of the characteristics of the mixed polymers due to the compounding of the compatibilizing agent is prevented. In such a case that the compatibilizing agent is contained, even when a block copolymer, a graft copolymer or a random copolymer is utilized and a polymer alloy is produced by generating chemical reaction at the time of kneading in a molten state, a stable phase state can be obtained and a uniform mixed state can be obtained. |
