Sum frequency generation spectroscopy (SFG) and attenuated-total-reflection IR (ATR-IR) were used to investigate polymer adsorption on solid surfaces in CCl4 (neutral), CHCl3 (acidic), and acetone (basic) solvents. Fowkes showed that the ad...
Noncopolymerization Approach to Copolymers via Concurrent Transesterification and Ring-Opening Reactions [0.03%]
通过同时进行酯交换和开环反应实现共聚物的非共聚方法
