Effect of Swelling Properties in Polymers at Different Temperature

Abstract

This research aims to define the swelling property in terms of weight change and evaluate its effect on polymer. The experimental work has been conducted in solid state physics laboratory at Sudan University of science and Technology College of science, swelling property was studied on two types of polymers rubber and plastic where two different rubber samples were used sample one containing high carbon black (external car tire), other sample lower percentage of carbon black (internal car tire). Two samples were taken from plastic bags, one containing carbon black and other does not. The above samples were placed in gasoline, acetone and benzene at room temperature for different period’s time as well as water at different temperature. Found the swelling property was higher in benzene from rubber containing carbon black either plastic was found high swelling in acetone at room temperature. In water found the percentage of swelling high in both rubber and plastic at different temperature
