Lyuinstra notes the dependence of properties of PPC synthesis of catalysts and comonomers. It also discusses the destruction of the polymer properties in vivo. 5 Conclusions Polymers based on renewable sources came a long time. Undoubtedly, these materials will play an increasingly important role in the consumer plastics, and will continue to be widely used in niche areas of health. Perhaps the reason this will not only economic and environmental benefits, but also a new profile properties that can demonstrate the polymers based on renewable resources, such as biocompatibility and degradability in vivo. Basic research in this area is actually just beginning. It is important to uncover the relationship between structure and properties of these new plastics, and, in particular, to develop effective methods predicting the properties of their destruction.
Another obstacle is that the polymer industry in its present form is based almost exclusively on materials from petrochemical raw materials. New renewable raw materials are not traditional polyolefin materials, and silnookislenny carbohydrate. Carbohydrate chemistry in the last century has focused on the development of sophisticated methods of protection or its removal, which could be used in pharmaceuticals / medicine. For use in plastics require the discovery and development of carbohydrate transformations, characterized by a small number of stages and high efficiency. Promising area for future development are the catalyst compositions, such as dehydration or carboxylation carbohydrate. There is also a lot of problems for the processing and transformation of these new raw materials, as well as control the properties of the polymers obtained economically and environmentally sensible methods.
In the short term improvement and development of reactions such as esterification, etherification and redox reactions of carbohydrates allow for the introduction of renewable raw materials in plastics. In the longer term, greater importance is the use of lignocellulosic feedstocks or mixed flows of biomass in the waste, as they significantly reduce costs. We are optimistic about the future of polymers based on renewable resources. There have been many important discoveries (Especially in the last ten years), and even more are expected in the future. Despite the fact that renewable polymers are not considered as emergency replacement of polyethylene or polypropylene, in the future production of their penetration routine and special products will become more apparent.
