Next Generation of Biodegradable Core- Shell Capsules

欧盟关于合成聚合物颗粒的微塑料法规要求淘汰不可生物降解的胶囊材料。大多数用于农药核壳胶囊配方的聚合物是基于二异氰酸酯和多胺的界面聚合，并且不可生物降解。FMC开发了独特的生物降解化学，该项目旨在开发多种配方的批量和连续工艺选择，每种配方都有自己独特的考虑因素：测试和选择合适的设备，开发优化收率和动力学的参数窗口，并向化学家提供成分选择的反馈。本项目可采用CFD和控制技术进行工艺优化或工艺模拟。这项工作将用于建立化学和工艺知识产权。实验工作将在特拉华州纽瓦克的斯坦研究中心进行。

EU microplastics regulations on synthetic polymer particles requiresphasing out non-biodegradable capsule materials. Most polymers usedfor core-shell capsule formulations of pesticides are based oninterfacial polymerization using diisocyanate and polyamines and arenot biodegradable. FMC has developed unique biodegradablechemistry and this project aims to develop batch and continuousprocess options for multiple formulations, each with their own uniqueconsiderations: testing and selecting appropriate equipment,developing parameter windows for optimized yield and kinetics, andproviding feedback to the chemist on ingredient selection. This projectcould take the direction of process optimization or process simulationvia CFD and control. This work will be used to build an IP estate forchemistry and process. The experimental work would be carried out atthe Stine Research Center in Newark, Delaware.
