摘要：
The polymer-polymer interaction in solution of the miscible polymer blend of bisphenol A polycarbonate/poly(methyl methacrylate) (PC/PMMA) is investigated by NMR methods. The inter-polymer H-1 nuclear Overhauser effects (NOE) can be observed, suggesting that PC and PMMA are in close contact with each other in solution. The C-13 spin-lattice relaxation time (C-13-T1) is measured for the mixture and pure polymers in solution. The temperature dependence of C-13-T1 is affected by mixing only for the phenyl and the methoxy carbon resonances. It is concluded that the phenyl group of PC and the methoxy group of PMMA interact with each other in solution.
