Simulation of ultrasonic degradation of macromolecules in solution

Title of program: USSI Catalogue Id: ACYN_v1_0 Nature of problem Two main aspects are to be considered in ultrasonic degradation of polymers in solution - what is the rate of chain breakage and where are the points of breakage located along the polymer chain. The study of the degradation process is based on the determination of the molecular weight distribution (polydispersity PDIS) and of the average molecular weights (number AMWN or weight AMWW) in function of the irradiation time. We have compared these experimental data with simulated values obtained by c ...
