Research Progress of Sustainable Monoterpene Polymers
With the growing demand for non-renewable resources such as fossil fuels,a large number of polymers are used every year in the form of plastics,most of which come from fossil fuels,so it is necessary to find new and renewable materials.Different from traditional petroleum-based polymer materials,bio-based polymer materials are a kind of green and environmentally friendly polymer materials synthesized from renewable biological resources,which have the characteristics of green source,cheap and easy to obtain and easy to degrade.Terpenes and terpenoids have unique chiral skeleton and active sites,which helps to replace fossil energy to make renewable and sustainable materials and reduce the burden on the environment,then expanding its application in biomedicine,packaging coatings,food industry and other fields.In this paper,the polymerization of monoterpenes,such as pinene,limonene and laurene,was reviewed,and the influence of different catalytic systems and temperature on the polymerization process was discussed,as well as the application of the obtained polymers in production and life and the future utilization of monomers.
