The terpene‐based monomers and polymers reported in the literature are mostly hydrophobic and this is limiting their use in aqueous environments. To address this drawback, we have developed a novel synthetic strategy to functionalise a model terpene monomer in order to improve hydrophilicity and the number of polar groups on the polymer side chains. To produce a highly hydrophilic monomer, carvone (meth)acrylate was chosen as the primary feedstock. Carvone has more functionalisable double bonds than other commercial cyclic terpenes and offers the potential for the maximum number of hydrophilic groups per monomer molecule. The monomers were homopolymerised and copolymerised to generate novel green hydrophilic and amphiphilic terpene‐based polymers which were characterised by ¹H–¹³C NMR, gel permeation chromatography, TGA and DSC analyses. © 2020 Society of Industrial Chemistry

新型香芹酮（甲基）丙烯酸酯单体的合成，用于生产高萜烯含量的亲水性聚合物

文献中报道的基于萜烯的单体和聚合物大多是疏水性的，这限制了它们在水性环境中的使用。为了解决这个缺点，我们开发了一种新颖的合成策略来对模型萜烯单体进行功能化，以提高亲水性和聚合物侧链上极性基团的数量。为了生产高度亲水的单体，选择了香芹酮（甲基）丙烯酸酯作为主要原料。香芹酮比其他市售的环状萜烯具有更多的可官能化双键，并为每个单体分子提供最大数目的亲水基团提供了潜力。单体均聚并共聚，生成新颖的绿色亲水和两亲萜烯基聚合物，其特征为¹ H– ¹³13 C NMR，凝胶渗透色谱法，TGA和DSC分析。©2020工业化学学会
