Polysulfide-derived polymers with a controllable density and mechanical strength were designed and prepared successfully using bio-based cottonseed oil (CO) and its derivatives, including fatty acid of cottonseed oil (COF) and sodium soap of cottonseed oil (COS). The reaction features of CO, COF and COS for polysulfide polymers were investigated and compared. Based on the free radical addition mechanism, COF reacts with sulfur to generate serials of polysulfide-derived polymers. COF strongly influences the density and tensile strength of these polymer composites. Whereas COS was not involved in the reaction with sulfur, as a filler, it could increase the density and tensile strength of polysulfide-derived polymers. Moreover, the results showed that these samples had an excellent reprocessability and recyclability. These polysulfide-based polymers, with an adjustable density and mechanical strength based on CO and derivatives, could have potential applications as bio-based functional supplementary additives.
利用生物基棉籽油(CO)及其衍生物,包括棉籽油脂肪酸(COF)和棉籽油钠皂(COS),成功设计并制备出密度和机械强度可控的多硫化物衍生聚合物。研究并比较了CO、COF和COS用于多硫化物聚合物的反应特性。基于自由基加成机理,COF与硫反应生成一系列多硫化物衍生聚合物。COF对这些聚合物复合材料的密度和拉伸强度有很大影响。而COS不参与与硫的反应,作为填料,它可以提高多硫化物衍生聚合物的密度和拉伸强度。此外,结果表明这些样品具有优异的再加工性和可回收性。这些基于CO及其衍生物的密度和机械强度可调的多硫化物基聚合物,作为生物基功能辅助添加剂可能具有潜在应用。
