Performance evaluation of polymeric blend of vinyl acetate and acrylate-based copolymers in lubricating oil

Abstract

Polymer modification processes like blending has attracted much attention as an easy, cost-effective and less time-consuming method for developing new polymeric materials enriched with versatile commercial application. Polymer blends are supposed to carry better thermal and mechanical properties compared to their parent polymers. In this view we have prepared a polymer blend of two copolymers– one of vinyl acetate and octyl acrylate and another of methyl methacrylate and dodecyl acrylate and characterized them by FT-IR and NMR spectroscopy. The molecular weight was determined by Gel Permeation Chromatography (GPC). We represented here a comparative study of their mechanical property as well as their performance as flow improver.
