PALACIO, Oscar; BUITRAGO, Oscar Y  and  DELGADO, Arnoldo E. Evaluation of Maleated Polyethylene in Ethylene Vinyl Acetate and Telinne Monspessulana Flour Composites. Inf. tecnol. [online]. 2016, vol.27, n.1, pp.139-146. ISSN 0718-0764.

The effect of the addition of maleated polyethylene to compounds of ethylene vinyl acetate with Telinne Monspessulana flour previously mercerized was investigated. Two factors were analyzed: (ii) concentration of maleated polyethylene with five levels 2; 4; 6; 8; 10 parts per hundred polymer; and (ii) concentration of flour with two levels 25 and 40 parts per hundred of polymer. The effect of maleated polyethylene on compatibility between ethylene vinyl acetate and flour was evaluated by tensile testing of compounds. Analysis indicates that the coupling agent improved the compatibility between Telinne Monspessulana flour and ethylene vinyl acetate, effect that was observed by the values of tensile strength and Young’s modulus. Based on these results, maleated polyethylene is a good alternative as a coupling agent in ethylene vinyl acetate and natural fibers compounds.

Keywords : ethylene vinyl acetate; Telinne Monspessulana; tensile properties; coupling agent.
