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
