Polymerization Mechanism and Kinetics of 1,1-Disubstituted Monomers. This project focuses on two exciting research areas: (I) we have found that an oxygen atom b to the double bond activates radical polymerization, making a whole new family of polymeric structures accessible, and (II) we have strong preliminary data that demonstrates a very large solvent effect on propagation and termination reactions for acrylic monomers with an a-CH2OH functionality, suggesting that significant control can be exerted over the polymerization process using additives. Additionally, we demonstrate that polymers containing repeat units with an a-CH2OH functionality can undergo reversible cyclization, enabling a whole range of novel functional materials.

1，1-二取代单体的聚合机理及动力学。该项目侧重于两个令人兴奋的研究领域：（I）我们已经发现双键的氧原子B激活自由基聚合，使得可获得全新的聚合物结构家族，和（II）我们具有强有力的初步数据，其证明了对于具有a-CH 2 OH官能团的丙烯酸单体的增长和终止反应的非常大的溶剂效应，这表明可以使用添加剂对聚合过程进行有效控制。此外，我们证明了含有具有a-CH 2 OH官能度的重复单元的聚合物可以进行可逆环化，从而实现整个范围的新型功能材料。
