The synthesis of polysilylethers (PSEs) using a monomer derived from a biorenewablefeedstock is reported. The AB‐type monomer was synthesized from undecenoic acid through hydrosilylation and reduction, and the polymerization was catalyzed by earth‐abundant metal salts. High‐molar‐mass products were achieved, and the degree of polymerization was controlled by varying the amount of an AA‐type monomer
报道了使用衍生自生物可再生原料的单体合成聚甲硅烷基醚(PSE)。AB型单体是由十一碳烯酸通过氢化硅烷化和还原反应合成的,并且聚合反应是由富含土的金属盐催化的。获得了高摩尔质量的产物,并且通过改变反应中AA型单体的量来控制聚合度。PSE具有良好的热稳定性和较低的玻璃化转变温度(T g ≈−67°C)。为了证明PSE的效用,聚氨酯是由低摩尔质量的羟基telechelic PSE合成的。
