Abstract

The invention discloses application of hyperbranched poly(amide amine)s in plastic processing, and belongs to the technical field of plastic processing agents. The application provided by the invention comprises the steps of uniformly mixing 0.1 to 5 parts by weight of amino-terminated hyperbranched poly(amide amine)s and 100 parts by weight of plastic, performing extrusion pelletization, and drying to obtain a modified plastic product. According to the application provided by the invention, the hyperbranched poly(amide amine)s is taken as a processing agent of the plastic of PPC, PP, PE, PA and the like, the outer layer of a hyperbranched poly(amide amine)s molecule contains a large number of active functional groups, and is low in melt viscosity, by adding the hyperbranched poly(amide amine)s into plastic substrates of PPC, PP, PE, PA and the like, the effective melt viscosity of a plastic system can be significantly reduced, namely the processing temperature and thermal degradation are decreased; in addition, such enhanced melt fluidity can still be realized through a lower additive amount, a finished film can be more easily extruded out, and the tensile strength and the processing performance of the plastic of PPC, PP, PE, PA and the like are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of plastic processing aids, in particular to the application of hyperbranched polyamidoamine in plastic processing. Background technique [0002] Hyperbranched polymer (HBP) is a new type of polymer material, which has the characteristics of three-dimensional structure, regular molecular structure and narrow relative molecular mass distribution. HBP has a compact structure similar to a sphere, and the molecular chains are less entangled, so the viscosity changes little with the increase of the relative molecular weight, and because there are many functional end groups in the molecule, the viscosity, solubility, thermal stability, glass transition temperature and the relative molecular weight distribution and other properties have a great influence. Hyperbranched polymers have a dendrimer-like structure (tree-like structure) and, due to their resemblance to dendrimers, possess similar physical properties as ...
