摘要:
AbstractAn equation is developed for calculating the fractures/chain link from the change in weight‐average molecular weight for the case of the photochemical degradation of a polymer with an initial random molecular weight distribution. From calculations made on the degradation of cellulose with 2537 A. light, it appears that the formation of aldehyde groups and the evolution of hydrogen are in part due to reactions not involving chain scissio
