Binary Blends of Ethylene-α-olefin Elastomers for Improving the Balance between the Impact Strength and Individual Deformation and Strength Properties of Polypropylene Composites Produced by Reactive Extrusion
The authors established and studied the synergistic effect of an increase in the impact strength and in individual physicomechanical characteristics of an elasticised polypropylene (PP) composite by using a binary combination of ethylene-α-olefin elastomers with contrasting Mooney viscosity values during reactive melt modification by the action of an organic peroxide and a coagent – trimethylolpropane triacrylate (TMPTA).
