Plastics derived from petroleum-based polymers offer affordable packaging, adhesives, building materials, computer components, and sporting and safety equipment. The durability and stability of these materials, however, has resulted in an undesirable accumulation of discarded plastics in our environment. The NSF Center for Sustainable Polymers (CSP) addresses this challenge by designing functional and environmentally sustainable plastics. Key aspects of sustainability include making plastics from renewable resources, using green and sustainable reaction chemistries, and making specialty plastics that can be composted or recycled after their use. CSP seeks detailed understanding of the chemical transformations happening in all of these processes, building a body of knowledge that can be generalized to other systems. The multi-institutional and collaborative team involves researchers from the University of Minnesota Twin Cities, Cornell University, Northwestern University, Washington University in St. Louis, University of California Berkeley, University of Chicago and University of South Dakota. CSP promotes innovation through technology transfer and entrepreneurship as demonstrated by their patent portfolio and spin-off companies. CSP has extensive programs in education, outreach, and broadening participation of underrepresented groups in the sciences. Their efforts include developing new college curricula and laboratory experiments with sustainable polymer examples. CSP-supported graduate students and postdoctoral researchers access professional development opportunities in communication skills, creating collaborative and equitable work environments, project management, and engaging with industry researchers. A diverse group of undergraduates is supported through summer research opportunities. A national partnership is bringing science skills and discussions of sustainable plastics to 4-H groups across the country. The NSF Center for Sustainable Polymers (CSP) incorporates experts in all stages of polymer chemistry that range from developing polymers from renewable resources, creating new chemistries for synthesis, and improving the recycling or degradation pathways for plastics after use. CSP's research efforts are organized into three areas that have substantive scientific overlap: 1) to discover new, efficient, and often catalytic chemical transformations of biomass and other natural product-based feedstocks into both new and established polymer ingredients; 2) to discover new sustainable polymers with precisely controlled molecular structures and establish relationships between structure, morphology, and performance properties; and 3) to discover sustainable polymers with triggered degradation, chemical recycling, and compatibilization capabilities to reduce or eliminate plastic waste. Center members emphasize research translation and the protection of intellectual property in their innovation efforts. The center trains and develops a diverse cohort of chemists that works collaboratively and leverages one another's expertise. CSP partners with youth development organizations to encourage interest in the physical sciences and engages the public in the challenges and the opportunities presented by sustainable polymers. CSP works to advance data sharing and reuse by making original, primary data files available with all publications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

源自石油的聚合物的塑料提供负担得起的包装，胶粘剂，建筑材料，计算机组件以及运动和安全设备。然而，这些材料的耐用性和稳定性导致我们环境中废弃的塑料的积累。 NSF可持续聚合物（CSP）通过设计功能和环境可持续塑料来应对这一挑战。可持续性的关键方面包括使用可再生资源制作塑料，使用绿色和可持续的反应化学作品，以及制作可在使用后可以堆肥或回收的特殊塑料。 CSP寻求对所有这些过程中发生的化学转化的详细理解，建立了可以推广到其他系统的知识体系。多机构和合作团队涉及明尼苏达大学双城，康奈尔大学，西北大学，华盛顿大学，圣路易斯，加利福尼亚大学伯克利分校，芝加哥大学和南达科他大学。 CSP通过技术转移和企业家精神促进创新，其专利组合和衍生公司证明。 CSP在教育，外展和扩大代表性不足的群体中的参与方面有广泛的计划。他们的努力包括开发新的大学课程和实验室实验，其中包括可持续的聚合物实例。由CSP支持的研究生和博士后研究人员在沟通技巧方面获得专业发展机会，创造了协作和公平的工作环境，项目管理以及与行业研究人员的互动。通过夏季研究机会，支持了一群多样化的本科生。全国性的伙伴关系是将科学技能和对可持续塑料的讨论带入全国4-H组。 NSF可持续聚合物中心（CSP）将专家纳入了聚合物化学的各个阶段，范围从可再生资源开发聚合物，创造了合成的新化学物质，以及改善使用后塑料的回收或退化途径。 CSP的研究工作分为具有实质性科学重叠的三个领域：1）发现生物质和其他基于天然产品的原料的新的，高效且经常催化的化学转化为新的和已建立的聚合物成分； 2）发现具有精确控制的分子结构的新的可持续聚合物，并在结构，形态和性能特性之间建立关系； 3）发现具有降解，化学回收和兼容功能的可持续聚合物，以减少或消除塑料废物。中心成员在创新工作中强调研究翻译和保护知识产权。该中心训练并发展了各种各样的化学家队列，这些化学家会合作，并利用彼此的专业知识。 CSP与青年发展组织合作，鼓励人们对物理科学的兴趣，并参与公众参与可持续聚合物带来的挑战和机会。 CSP致力于通过所有出版物提供原始的主要数据文件来推动数据共享和重复使用。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来获得支持。
