Synthesis and characterization of renewable cellulose based plasticizer for polyvinyl chloride (PVC)
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Acid catalyzed liquefaction of brown paper handtowel was performed using a mixture of diethylene glycol and glycerol andaddition of minute amount of p-toluenesulphonic acid as a catalyst. TheLiquefied brown paper was used as a polyhydroxy alcohol during the estersynthesis as large number of hydroxyl groups is available in liquefied brownpaper products. Esterification was performed by using hexanoic acid along withdibutyl tin (IV) oxide as a catalyst. The product was characterized by usingFTIR, SEC and SEM. PVC films were prepared by solution casting. They wereplasticized by the prepared liquefied brown paper ester and by traditionaldiisooctyl phthalate. Comparison of both plasticizers on the basis ofmechanical, thermal properties and plasticizer migration was elaborated.
