Abstract

The invention relates to a method for synthesizing a polyketone high polymer material via the copolymerization of pinene and carbon monoxide under catalysis of transition metal, comprising the step of copolymerizing pinene and carbon monoxide in a high-pressure kettle to obtain the polyketone high polymer material with a novel structure by taking o-chlorophenol and methanol as solvents at carbon monoxide pressure of 2-6MPa and reaction temperature of 30-80DEG C under the action of a catalytic system formed by strong acids such as palladium chloride or palladium acetate, benzoquinone, trifluoromethanesulfonic acid and the like. The invention provides a method for preparing the degradable high polymer material via natural forest resources and chemical exhaust gas. The method in the invention completely dispenses with the dependence of the polyketone synthesis on the non-renewable resources such as oil, natural gas and the like; and the synthesized polyketone high polymer material keeps the unique ring-shaped molecular structure feature of the pinene, has excellent natural degrading characteristic and biocompatibility, and can be widely applied to the industries such as agriculture, medicine, life and the like.

Description

technical field [0001] The invention relates to a method for copolymerizing pinene and carbon monoxide under transition metal catalysis to form polyketone polymer materials. It belongs to the field of polyketone synthesis. technical background [0002] Copolymerization of carbon monoxide and olefins to prepare environmentally friendly polyketones not only makes full use of abundant and cheap one-carbon resources, but also provides a new idea for the preparation of multifunctional, bio / photodegradable olefin copolymers, which is a broadly attractive research field . The performance and application of polyketone products are closely related to the molecular structure and composition of polyketones. The molecular structure and composition of polyketones can be adjusted by the difference of olefin monomers. Currently, monomers for copolymerization with carbon monoxide are often aliphatic α-olefins, such as ethylene, propylene, etc., and aromatic α-olefins, such as styrene. I...
