The effect of electron beam irradiation in presence Of TMPTA as an initiator on tensile properties of linear low density polyethylene/poyl(vinyl alcohol) blends

摘要

The effect of electron beam (EB) irradiation on the thermal and tensile properties of unmodified and modified linear low density polyethylene/poly(vinyl alcohol) (LLDPE/PVA) blends with trimethylolpropane triacrylate (TMPTA) were investigated irradiated at 50, 100 and 150 kGy. The LLDPE/PVA blends were prepared by melt mixing. LLDPE/PVA (php/php) blends ratio between 90/10 to 40/60 was studied. The effects of TMPTA on gel content, FTIR and tensile properties of LLDPE/PVA blends were investigated. The results indicated that, the presence of TMPTA increased the tensile properties compared to blends without TMPTA due to more crosslinking formation. The degree of crosslinking was quantified by gel content measurements and verify with FTIR analysis.
