Abstract
The results of an infrared spectroscopic characterization of poly(viny l cinnamate) (PVCIN) and its blends with poly(4-vinyl phenol) (PVPh) a re reported before and after photo-crosslinking the PVCIN by exposure to UV radiation. The purpose of this article is to demonstrate methodo logy, and it is shown that quantitative analysis of the fraction of un saturated (-C=C-) double bonds, ''free'' (non-hydrogen bonded) and hyd rogen bonded unsaturated (-CO-C=C-) and saturated (-CO-C-C-) acetoxy c arbonyl groups is feasible in these blends as a function of UV exposur e time.
