Abstract
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 1H nuclear Overhauser effects (NOE) can be observed, suggesting that PC and PMMA are in close contact with each other in solution. The 13C spin-lattice relaxation time (13C-T1) is measured for the mixture and pure polymers in solution. The temperature dependence of 13C-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.
