摘要

Cross-linked poly (methyl methacrylate)(PMMA) was synthesized to high conversion with 0.02-0.5 wt% 13C-or 2H-labeled ethylene glycol dimethacrylate (EGDMA). Samples were analyzed with a variety of NMR techniques to examine different cross-linker reaction products (or architectures), ie, pendant EGDMA methacrylates, cyclized EGDMA, and cross- linked EGDMA. Solid-state 13C NMR spectroscopy was not applicable because poor ...
