【概要の説明】In blends of immiscible polymers, compatibilization is typically required to improve the adhesion between the phases. The maleic anhydride graft polymer is formed during the melt blending process by reacting a reactive polymer in situ. Miscible with one of the blend components, MAH also reacts with the functional group of the second component to form an in situ block graft copolymer. The copolymer is generated at the interface can greatly improve the dispersibility and reduce the size of dispersed phase.

詳細
Blending of immiscible polymers provides an economical, versatile method for developing new polymeric materials with special properties. A key step to control the microstructure and properties of this material is to optimize processing conditions based on the flow characteristics of the material.
 
In blends of immiscible polymers, compatibilization is typically required to improve the adhesion between the phases. The maleic anhydride graft polymer is formed during the melt blending process by reacting a reactive polymer in situ. Miscible with one of the blend components, MAH also reacts with the functional group of the second component to form an in situ block graft copolymer. The copolymer is generated at the interface can greatly improve the dispersibility and reduce the size of dispersed phase. The mixture of nylon and polyolefin elastomers has a lower viscosity when the ratios of the two are similar, and a large difference is an increase in viscosity due to the structure caused by interface slip. The size of the dispersed phase in which the compatibilizer is added becomes small, and there will be no significant change until 10%. The viscosity increases with the addition of 1% of the compatibilizer, and then the viscosity of the compatibilizer increases little.
