Grafting of n-vinyl-2-pyrrolidone over polyethylene by gamma irradiation: preparation and characterization
- 1. Instituto de Pesquisas Energeticas e Nucleares (IPEN), Sao Paulo, SP (Brazil)
Description
Some parameters for the preparation of low density polyethylene films (LDPE) grafted with N-Vinyl-2-pirrolodona (NVP) by the simultaneous irradiation method were determined. The concentration of NVP for a grafting degree of 69% (maximum) was 60% (v/v), at a irradiation dose of 0,823 KGy at 270 C. Infrared spectroscopic measurements of the grafted LDPE films showed the appearance of characteristic bands of the NVP structure. (author)
