Nano-sized silica was pre-grafted with poly(glycidyl methacrylate) (PGMA) by solution free-radical polymerization. When these grafted silica particles were melt compounded with polypropylene (PP), reactive compatibilization effect was perceived due to the chemical bonding between the PGMA and amine functionalized PP, which led to a significant increase of tensile strength and notch impact strength of PP at rather low filler content. Accordingly, compatibility of each kind of the functionalized PP with grafted SiO2 was evaluated through investigating the mechanical properties, crystallization behavior and rheological performance of the composites. The results show that the reactive compatibilization is capable of providing stronger interfacial adhesion.

The Impact

Abstract A melt blending process was used to prepare poly(lactic acid) (PLA)/metallocene catalyzed polyethylene octene copolymer (POE) blends in order to toughen PLA. A commercialized ethylene-glycidyl methacrylate copolymer (EGMA) was applied as a compatibilizer to improve the dispersion and interaction of dispersed POE to the PLA matrix. The results showed that chemical interaction seems to be the driving force for reinforcing the compatibility between PLA and POE, and also the dispersion of POE into the PLA matrix domain. With the incorporation of 10 phr EGMA in the blends, POE was well-dispersed at a sub-micrometer scale within the PLA matrix, indicating better interfacial compatibility between PLA and POE. The impact strength test revealed that POE could significantly toughen PLA containing EGMA in the blends, up to no-break level regarding unnotched Izod impact strength at 10 phr EGMA content. With the increase of EGMA content, the blends showed lower tensile strength, but higher elongation at break due to the elastomeric characteristics of EGMA. When 10 phr of the EGMA was incorporated into the blends, its elongation at break reached 54.5%, 10.7 times that of neat PLA at 5.1%. The melt viscosity of compatibilized blends containing 10 phr EGMA increased by more than 50% in comparison with the non-compatibilized blend, which implied a good interfacial interaction between the PLA and POE interface.

Anchoring Strength

Compatibilization between polypropylene(PP) and wood-flour was achieved by means of direct reactive extrusion of glycidyl methacrylate(GMA), PP, wood-flour, and other additives. Impact cracking surfaces of the PP/wood-flour composites(WPCs) was observed via scanning electron microscope(SEM), and mechanical properties of the WPCs were tested. The effect of comonomer styrene(St) and antioxygen triphenyl phosphite(TPP) on the reactive compatibilization was also evaluated. Experimental results indicated that the anchoring strength of interface in the composites was obviously strengthened after direct reactive extrusion. The tensile and flexural strength of the WPCs were obviously improved, but the elongation at break and notched impact strength slightly declined after reactive compatibilization by GMA and dicumyl peroxide(DCP). The addition of St and TPP improved the mechanical properties of the WPCs. At 1.5% of GMA, 0.3% of DCP, 1.5% of St and 1% of TPP in the extrusion composition of WPC, the tensile strength, flexural strength, elongation at break and notched impact strength respectively increased by 39%, 31%, 28% and 29% comparing to those of the WPC without reactive extrusion.
