摘要: Abstract On the basis of correlation data obtained by broad-line n.m.r. and magic angle spinning analysis as well conformational analysis, conclusions have been drawn concerning nature molecular motion occurring in a polycarbonate chain vicinity −60°C. It is postulated that this connected with reorientation bisphenol unordered chains random conformation.
