Abstract
Polymethyl methacrylate (PMMA) is widely used as a substitute for glass, known as organic glass. During the processing and after use, there are amount of castoff. Based on the similar framework, PMMA could be useful feed stock to synthesis poly methacrylamide (PMAA) used for crude oil additive. In this work PMAA was prepared by aminolysis reaction of PMMA and aliphatic amines. The performance of PMAA on heavy oil was evaluated as pour point depressant as well as paraffin inhibiter. The highest pour point reduction depression was achieved as 12.1°С with the dosage of 600 ppm PMAA 1. Differential scanning calorimetry and paraffin crystal morphology studies were conducted to elucidate the mechanism of pour point reduction.
