Polypropylene thermal degradation
WebNow, a team led by Eugene Chen at Colorado State University, US, has developed a synthetically modified PHA that demonstrates both high thermal stability and complete chemical circularity. ‘We took a fundamental approach to substitute the two labile hydrogen atoms at the α,α-position to prevent decomposition by cis-elimination at high … Webthermal degradation rate of the materials will be lower [6]. Upon the promising outcomes in the thermal area of PP/PC blends, more research is needed in order to comprehend the matter. Subsequently, this work is aimed to characterize the thermal properties and morphology of PP/PC/PP-g-MA polymer blends of various compositions.
