A photocrosslinkable water-soluble polymer has been prepared by partial esterification of poly(vinyl acetate-co-vinyl alcohol) with cinnamic acid. The photochemical [2 + 2] cycloaddition reaction has been used as a chemical probe for the investigation of different conformational states of the polyme

Variations, as a function of temperature, are reported in the magnitude of values for the partial molal volume, partial molal expansibility, flowing volume and surface pressure for dilute solutions of a series of poly(vinyl alcohol-co-vinyl acetate) copolymers of various vinyl acetate contents and a
## Abstract Electron beam (EB) irradiation of polyvinyl chloride (PVC) was carried out in the presence of three different ethyleneβvinyl acetate copolymers (EVA). The mechanical properties of the original and irradiated blends were tested. The gel content measurement, chlorine loss upon electron ir
Values for the partial molal volumes (~v) of a series of poly(vinyl alcohol-co-vinyl acetate) copolymers, obtained from the same parent poly(vinyl acetate) but of differing degrees of hydrolysis and block size distribution, were obtained from high precision density measurements. An analysis of the d
By irradiating dilute aqueous solutions of poly(vinyl alcohol) with t~sec-pulses of fast electrons, side-group macroradicals are formed and they are deactivated by combination and disproportionation. During the disproportionation, ---C(H)~---C(OH)---groups are formed in the main chain; they enable a
