论文摘要
在这项工作中，使用我们组中开发的大量金属催化剂来实现柠檬烯氧化物（LO）的聚合，该催化剂在打开环（ROP）过程中非常活跃。获得的基于生物的多氨基醚（PLO）具有低分子量和良好的热性能，因此对于其他基于Bio的聚合物（例如PLA）是潜在的绿色聚合物添加剂。因此，我们探索了它影响PLA性能的能力。仅增加10 wt％，从而在灵活性，热稳定性和疏水性方面导致了PLA性能的修改和改善。获得的结果是有希望的，并打开了基于PLA/PLO的混合物的融化，氧化多氧化物（PLO）的潜在工业应用。这些新材料完全基于可再生能源，对于需要生物降解性和减少水吸附的许多应用，例如食品包装或农业覆盖膜。
In this work, the polymerization of Limonene Oxide (LO) has been achieved using an Earth abundant metal-based catalyst developed in our group, that is very active in ring opening polymerization (ROP) processes. The bio-based polylimonene ether (PLO) obtained had low molecular weight and good thermal properties, thus being a potential green polymeric additive for other bio-based polymers such as PLA. Hence, we have explored its ability to influence PLA properties. The addition of only 10 wt %, led to the modification and improvement of PLA properties in terms of flexibility, thermal stability, and hydrophobicity. The results obtained are promising and open up the potential industrial application of polylimonene oxide (PLO) for the melt-processing of blends based on PLA/PLO. These new materials are totally based on renewable sources and may be interesting for many applications where biodegradability and reduced water adsorption is required, such as food packaging or agricultural mulch films.
