松香基功能性单体的合成及应用

摘要

Rosin is one of the most important forestry resources in China. The main components of rosin include different resin acids. As raw material,it can take part in various reactions to synthesize functional monomers in polymer science field because of its unique chemical structures including double bond and carboxyl group. The rosin can be widely applied in painting,adhesive,aerospace, and other fields. Due to low cost,superior mechanical and thermal properties,as well as environmental friendly and renewable alternative,rosin has drawn wide public attention in polymer science field. This article reviewed the rosin-based functional monomer containing acrylate group,vinyl group,and allyl group,respectively. Its application was mainly discussed in polymer and other new material areas including polyurethane resins,epoxy resins,phenol-formaldehyde resin,organic silicone resin and unsaturated polyester. Based on the rosin-based functional monomers,a series of rosin derivatives as application of new application materials were explored,and provided new perspectives for the novel surfactants,cross-linking agents,shape memory materials and other new fields. Moreover,the prospective direction of rosin-based polymer materials was given.%松香是我国重要的林业生物质资源，主要成分为松香树脂酸。由于松香分子结构中含有双键和羧基，可经多种反应途径合成功能性单体制备高分子材料，广泛应用在涂料、胶黏剂、航空航天等领域中。由于松香价格低廉、力学性能与热性能优越，同时具有环境友好、可再生等优点，在高分子领域引起了广泛的关注。论文分别对丙烯酸酯类、乙烯基酯类及烯丙基类的改性松香功能性单体的合成进行了综述，重点论述了在聚氨酯树脂、环氧树脂、酚醛树脂、有机硅树脂和不饱和聚酯等领域的应用。针对松香基功能性单体的深度研究，探讨了一系列由松香基衍生物参与的新型材料的应用，为新型表面活性剂、交联剂、形状记忆类材料等领域的发展提供了新的视角。最后，论文对未来松香基高分子材料合成研究的方向进行了展望。
