Abstract

The invention relates to a biologic polyamide quadripolymer and a synthesis method thereof, and belongs to the field of high molecular materials. The biologic polyamide quadripolymer is characterized in that the structural formula is shown as the specifications, wherein the four chain segments or chain links are arranged randomly. The invention also provides the synthesis method. The biologic polyamide quadripolymer has excellent environmental stability, a thermal crosslinking property, an irradiation crosslinking property and solvent corrosion resistance, and has physical and mechanical properties and a processing property which are equal to those of conventional polyamide.

Description

technical field [0001] The invention relates to an aliphatic polyamide tetrapolymer containing a C=C double bond in its molecular structure and a preparation method thereof, in particular to a preparation method of a bio-based polyamide based on renewable resources, belonging to the field of polymer materials . Background technique [0002] At present, human society's demand for energy and materials is highly dependent on the ever-decreasing non-renewable fossil resources. serious problems such as sharp decline and environmental pollution. Polymer materials play a very important role in modern social life due to their excellent performance and wide application. However, the sources of monomers of widely used polymer products such as plastics, rubber and fiber products are all dependent on non-renewable fossil resources. [0003] Polyamide (PA), also known as nylon, refers to a linear thermoplastic polymer with amide group (-CONH) repeating structural units on the main cha...
