The influence of mixing order on the phase inversion and crystallization behavior of polyamide 6/maleic anhydride-g-ethylene–propylene–diene rubber/high-density polyethylene blend

In our experiments polyamide 6/high density polyethylene blends (25/75 wt%) were produced and maleic anhydride grafted polyethylene was used as chemical coupling agent. To get finer microstructure and enhance the mechanical properties the blends were compounded by different nanostructured reinforcements. Two kinds of nanosilicate, the layered structure montmorillonite and the needle like sepiolite were applied in different concentrations and their effect on the mechanical and melting properties were examined.

Vulcanizates of blends of ethylene-propylene-diene rubber (EPDM) and polyamide (PA) copolymer were prepared by reactive compatibilization. A reactive route was employed to compatibilize these blends by the addition of maleic anhydride EPDM (MAH-g-EPDM). In this paper, the influence of compatibilizers, crosslinking agents, and blend composition on the mechanical properties of the blends were investigated. The morphologies of the blends were determined by scanning electron microscopy. It was found that the addition of MAH-g-EPDM reduced the particle size of the dispersed phase remarkably. The stability of the blend was measured by thermal ageing at high temperature in the presence of compatibilizer. Both dynamic mechanical thermal analysis and differential scanning calorimetry experiments were carried out to investigate the effect of MAH-g-EPDM addition on the Tgs of the blend components. The addition of PA copolymer caused significant improvement in the tensile properties of these blends.

This research aims to investigate the efficiency of polybutadiene-grafted maleic anhydride (PB-g-MAH) as the compatibilizer for ethylene-propylene diene rubber and epoxidized natural rubber (EPDM/ENR) blends. PB-g-MAH was varied from 0-10 parts per hundred parts of rubber (phr), and the cure characteristics, mechanical and dynamic properties of 70/30 EPDM/ENR blends with and without compatibilizer were evaluated. It was found that the minimum torque, maximum torque, scorch and cure times of the blends increased after adding PB-g-MAH, whereas cure rate decreased. The morphology of the blend is improved by the addition of PB-g-MAH in small amounts, owing to an improved compatibility of these rubbers confirmed by dynamic mechanical property. The hardness and oil resistance increased with increasing PB-g-MAH content. Of all blends investigated, the blend compatibilized with 2-4 phr of PB-g-MAH shows the optimum mechanical properties and thermal resistance.
