A rABS/PBT/ASG composite material and a preparation method thereof utilize the characteristics of rABS with carboxyl and hydroxyl groups, wherein rABS are pre-blended with ASG to increase the viscosity, so that the epoxy groups on the ASG molecules react with the hydroxyl groups and the carboxyl groups on the rABS, and the acrylonitrile-styrene segments in ASG and rABS are thermodynamically miscible, followed by reacting and blending with PBT to prepare the rABS/PBT/ASG composite material. ASG acts as a chain extender and solubilizer in the mixture. The mixture prepared in this way have good compatibility, and the tensile strength, impact strength and elongation at break of the composite material are comprehensively improved. The composite material obtained has the advantages of both ABS and PBT materials, which has broad application prospects in the field of ABS plastic recycling.

Provided is a process for preparing a PVDC additive blend in which an additive is blended with PVDC under high shear blending to produce a highly uniform blend in which the additive is homogeneously distributed throughout the PVDC. It has been found that performing high shear blending in multiple successive stages in which the concentration of the additive in the blend is reduced in each successive stage helps in prove the uniformity of the PVDC additive blend. For example, the high shear blending may be carried out in 2 to 6 stages, and in particular, from 2 to 4 stages. Also provided is a PVDC additive blend having a uniform blend of PVDC and an additive, such as a blend of a PVDC copolymer of vinylidene chloride and methyl acrylate and a fluorescing agent, such as 2,2′(2,5-thiophenylendiyl)bis(5-tert-butylbenzoxazole).

A production method for a low molecular weight polymer suitable for a melt-blown non-woven fabric and a production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage arranged in the axial direction inside the screw body.
