New Findings from University of Science Malaysia in the Area of Polyenes Described

June 26, 2014

By a News Reporter-Staff News Editor at Agriculture Week -- Current study results on Polyenes have been published. According to news reporting from Penang, Malaysia, by VerticalNews journalists, research stated, "The thermal, mechanical, and morphological properties of biobased thermoplastic starch (TPS) obtained from agricultural waste seed (AWS) and agricultural waste tuber (AWT) blended with polypropylene (PP) were investigated in this article. The grounded (pulverized) AWS and AWT were different in amylose/amylopectin ratios and contained relatively low starch content (

The news correspondents obtained a quote from the research from the University of Science Malaysia, "The commercial grade of TPS (CS) and native tapioca starch blended PP (NTS/PP) were also prepared for comparison. The performances of the TPS/PP blends were dependent on the starch composition (e.g., amylose-to-amylopectin ratio), particle size, dispersion, and interfacial adhesion with matrix. The high-amylopectin starch blend (i.e., AWS/PP) was more susceptible to thermal degradation than the amylose-rich material (i.e., NTS/PP)."

According to the news reporters, the research concluded: "The addition of starch to PP not only led to a stiffening effect (i.e., increase in storage modulus), but it also affected the relaxation of polymer matrix by shifting the thermal transition (i.e., glass transition temperature) to a higher temperature.
