Abstract Syntheses of novel hybrid PolyHydroxyUrethane (PHU)/siloxane polymers have been performed by sol-gel process in order to mix properties of organic and inorganic compounds. In the objective to replace Polyurethanes (PU) for environmental and health concern, Polyhydroxyurethanes (PHU) are becoming interesting candidates in Non-Isocyanate Polyurethanes (NIPUs) routes. Therefore, mixing PHU and siloxane monomers to synthesize hybrid organic/inorganic materials is a promising approach. In this way, Polyhydroxyurethanes prepolymers with trimethoxysilane end groups were firstly obtained via two synthetic pathways and finally cross-linked by sol-gel process. Trimethoxysilane groups can be grafted onto diamines or dicyclic-carbonates varying chemical structure and thus properties of final materials. Three different PHU hybrid bulk materials have been obtained and these thermosets have been characterized with DSC, ATG, SEM and DMA measurements.

溶胶-凝胶杂化聚羟基脲的合成

摘要 为了混合有机和无机化合物的特性，已经通过溶胶-凝胶法合成了新型混合聚羟基氨基甲酸酯 (PHU)/硅氧烷聚合物。为了取代聚氨酯 (PU) 以解决环境和健康问题，聚羟基聚氨酯 (PHU) 正成为非异氰酸酯聚氨酯 (NIPU) 路线中的重要候选材料。因此，将 PHU 和硅氧烷单体混合来合成有机/无机杂化材料是一种很有前景的方法。这样，首先通过两种合成途径获得了具有三甲氧基硅烷端基的聚羟基氨基甲酸酯预聚物，最后通过溶胶-凝胶工艺交联。三甲氧基硅烷基团可以接枝到二胺或二环碳酸酯上，改变化学结构，从而改变最终材料的性能。
