Using molecular explanations, discuss the differences in mechanical, physical, and chemical properties of natural rubber and butadiene
What will be an ideal response?
Natural rubber has a methyl group which interferes with movement restricting the bending, twisting, and sliding motions across the molecules and increases stiffness, gives a higher strength and higher temperature stability. Polybutadiene has poor tensile strength, tear resistance, poor resistance to solvents, and tack because of the lack of the methyl group.
