BLENDING COMPATIBILIZATION METHOD OF BIODEGRADABLE POLYMERS CAPABLE OF ENHANCING COMPATIBILITY BETWEEN POLYLACTIC ACIDS AND POLYCAPROLACTONE BY INTRODUCING GLYCIDYL METHACRYLATE TO A POLYLACTIC ACID/POLYCAPROLACTONE BLEND
BLENDING COMPATIBILIZATION METHOD OF BIODEGRADABLE POLYMERS CAPABLE OF ENHANCING COMPATIBILITY BETWEEN POLYLACTIC ACIDS AND POLYCAPROLACTONE BY INTRODUCING GLYCIDYL METHACRYLATE TO A POLYLACTIC ACID/POLYCAPROLACTONE BLEND
PURPOSE: A blending compatibilization method of biodegradable polymers is provided to facilitate the mixing between biodegradable polymers, to avoid property degradation caused by pyrolysis, and to control the commercialization by controlling the intensity of electron ray radiation. ;CONSTITUTION: A blending compatibilization method of biodegradable polymers comprises the steps of: blending a first polymer and a second polymer selected from the polymers having a carboxy group or a hydroxyl group at the terminals; adding a functional monomer having epoxy, maleic anhydride or isocyanate capable of fast condensation polymerization and double bond to the blend and melt-mixing a reaction mixture using an extruder; and irradiating electron rays to the molten mixture.;COPYRIGHT KIPO 2011
