Description

Poly(N-vinyl-2-pyrrolidone) (PVP) gels, crosslinked by irradiation, have been used for healing of wounds. In this work, a hydrophilic copolymer (dimethyl siloxanes and ethylene oxy - SEO), is added to PVP to improve the mechanical properties. The characterization was performed by DMA, showing that SEO increases the film flexibility, but an excess can inhibit the PVP crosslinking. Crosslinking with electron beam was more effective than with Co-60 source. (author). 5 refs., 2 figs
