Branching in bisphenol A polycarbonate has been investigated by fractionation, gel permeation chromatography, viscometry and light scattering. The samples studied (Makrolon 3000 and 3000L) are branched, Makrolon 3000 more so than Makrolon 3000L. The variation of the branching parameters with molecul

The physical aging of bisphenol A polycarbonate was studied using the differential scanning calorimetry technique. Cowie and Ferguson's model and Williams-Watts function were used to analyze the data. It is confirmed that the relation ⌬H Ο± (T a ) Ο­ ⌬C p (T g Οͺ T a ), where ⌬H Ο± (T a ) is the value o

Randomly branched bisphenol A polycarbonates (PCs) were prepared by interfacial polymerization methods to explore the limits of gel-free compositions available by the adjustment of various composition and process variables. A molecular weight distribution (MWD) model was devised to predict the MWD,
