In materials science, a polymer blend, or polymer mixture, is a member of a class of materials analogous to metal alloys, in which at least two polymers are blended together to create a new material with different physical properties.
[1] During the 1940s, '50s and '60s, the commercial development of new monomers for production of new polymers seemed endless.
In this period, it was discovered that the development of the new techniques for the modification of the already existing polymers, would be economically viable.
A new polymers modification process, based on a simple mechanical mixture of two polymers first appeared when Thomas Hancock created a mixture of natural rubber with gutta-percha.
