Study about plasma-induced graft poly merization of acrylic acid on LDPE film(Ⅱ)

In this paper, the surface of LDPE film was modified by cold plasma-induced graft reaction.

Grafting of acrylonitrile (AN) on chlorination polypropylene (CPP) by free radical process was carried out using toluence as solvent, benzoperoxide (BPO) as initiator and to prepare a kind of adhesive for BOPP film.

The results showed that the mechanical properties of the modified LDPE filmwere improved because of the improvement of the dispersity of the nano-CaCO 3 ,which was subjected to a certain surface treatment,in LDPE and surface ad-hension between nano-CaCO 3 particles and substrate.

Various initiators, including BP, Irgacure 651 and 184, ITX, XAN, AQ, BPO, AIBN, acetone and cyclohexanone, were used to initiate photo grafting vinyl acetate (VAC) onto LDPE film, which was applied as the substrate.

A variety of monomers, including AA, AN, AAM, BA, MA, MAA and MMA, were photografted onto substrate composed of two LDPE films, initiated by benzophenone(BP).
