Block and graft copolymers based on biobased polylimonenecarbonate with promising material properties

生物基聚合物如果不是从重要的原材料中获得，则特别具有可持续性。一种这样的聚合物是新开发的聚（柠檬烯碳酸酯），简称PLimC，其可以在通过金属络合物催化的柠檬烯氧化物与CO2的共聚而使柠檬烯（从橘子壳获得）环氧化之后获得。该PLimC的特征在于有前途的化学和物理性质概况。在该项目的背景下，将研究嵌段和接枝共聚物的新型合成方法，一方面通过复杂的聚合物结构显着扩展性能，另一方面通过相介质使PLimC也可用于与经典聚合物的共混物，以提高其可持续性。为了这些共混物的成功应用，将研究上述嵌段和接枝共聚物作为相介质。目的是通过控制共混物形态来实现至少令人满意的机械性能。PLimC的嵌段和接枝共聚物将系统地研究它们在溶液中和在固态中的形态结构以及它们的流变学和机械性能。在初步工作的范围内，我们已经取得了非常有趣的，有时令人惊讶的结果，关于PLimC嵌段共聚物的相形态。这些结果预计将导致有关生物基PLimC作为新物质类别的知识显着增加，以供进一步研究。我们期望该项目的结果将使PLimC成为一种新型的生物基材料。

Biobased polymers are particularly sustainable if they are not obtained from vital raw materials. One such polymer is the newly developed poly(limonene carbonate), PLimC for short, which can be obtained after epoxidation of limonene (obtained from organge shells) by metal complex-catalyzed copolymerization of limonene oxide with CO2. This PLimC is characterized by a promising chemical and physical property profile. In the context of this project, novel synthesis approaches to block and graft copolymers will be investigated in order to significantly extend the property profile by complex polymer structures on the one hand and to make the PLimC available by phase mediators also for blends with classical polymers on the other hand in order to improve their sustainability. For the successful application of these blends, the above-mentioned block and graft copolymers will be investigated as phase mediators. The aim is to achieve at least satisfactory mechanical properties by controlling the blend morphology. The block and graft copolymers of PLimC will be systematically investigated with respect to their morphological structure in solution and in the solid state as well as their rheological and mechanical properties. Within the scope of preliminary work, we have already achieved extremely interesting and sometimes surprising results with regard to the phase morphology of PLimC block copolymers. These results are expected to lead to a significant increase in knowledge about the biobased PLimC as a new substance class for further work. We expect that the results of this project will establish PLimC as a novel biobased material.
