On a sample of poly(methyl methacrylate) prepared by an anionic polymerization technique with sodium biphenyl in tetrahydrofuran at –78°C, abnormal cloud-point curves in nonpolar theta solvents, p-xylene, and carbon tetrachloride were observed. Th

A semi-empirical method for estimating unperturbed chain dimensions from relationships between intrinsic viscosity M and molecular weight M is proposed. This method is based on combining the Ptitsyn equation of the excluded volume effect with a semi-

The microwave-assisted direct polycondensation of LA to synthesize PLA has been studied. Microwave irradiation strikingly accelerates the polymerization rate of LA compared to conventional heating. By use of a binary catalyst of Sncl 2 /p-TsoH, PLA w
