摘要

A 300MHz solid NMR study on the compatibility of ACR (poly (methyl methacrylate-co-methacrylate)

in the ratio of 1:1)-PVC (poly (vinyl chloride)) blends is reported. Spin-lattice (T1) and spin-spin (T2) relaxation time of ACR

PVC and their blends are recorded in the temperature range from 215K to 355K. Experimental results indicate that ACR and PVC are compatible with each other and the domain size is smaller than 25 nm

but heterogeneit(?)s of molecular dimensions still exist. Some problems of mechanism of compatibility and data analysis are also discussed.
