MIP experiment on the melting temperature of different polymers

LDPE has the lowest average melting temperature (103.6°C) out of the 4 polymers. It is because LDPE is a linear polymer that has a branched structure which is able to expel the applied heat faster through the “branches” and melt faster. HPDE has the second lowest average melting temperature (139.5°C) out of the 4 polymers. Unlike LDPE, HDPE does not have a branched structure and the HPDE polymer chains are able to pack more tightly to one another. Therefore HPDE has a higher density than LDPE and is able to withstand more heat than LDPE. However HPDE and LDPE has lower average melting temperatures of 139.5°C and 103.6°C respectively than average melting temperature of PP(178.4°C) is due to the fact…
