Five kinds of aromatic polymers [polycarbonate(PC), polyarylate(PAR), polyetherimide(PEI), polysulfone(PSF), polyethersulfone(PESF)] were degraded at 380 Β° in vacuum. The molecular weights and molecular weight distributions of degraded samples were measured by gel permeation chromatography, using di
Bisphenol A polysulphone (PSF) and polyethersulphone (PESF) were photodegraded homogeneously at room temperature in an inert and a normal atmosphere. The average molecular weights and the molecular weight distributions of degraded samples were measured by means of GPC to evaluate the quantum yields
## Abstract A statistical theory of the parallel accumulation of randomly placed breaks and damage not associated with breaks in linear polymers is presented. Expressions for the weight fraction of polymer in the form of chains that bear __n__ or more sites of nonbreak damage (markers) are develope
