Abstract
Poly (4-vinyl pyridine) and its quaternized salts have been studied under electron beam. The electron beam sensitivity of poly(4-vinyl pyridine) was found to be increased upon both increasing molecular weight and decreasing molecular weight distribution. This was attributed to the crosslinking behavior of poly(4-vinyl pyridine) under electron beam. The electron beam sensitivity of poly(4-vinyl pyridine) was improved by several orders of magnitude by quaternizing. The relationship between the electron beam sensitivity and the degree of quaternization has been studied and several mechanisms have been postulated.
