Polymers 1. Introduction. Prior to the early 1920’s, chemists doubted the existence of molecules having molecular weights greater than a few thousand.
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance.
Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects.. Plasticity is the general property of all materials which can deform irreversibly without breaking but, in the class of moldable polymers, this occurs to such a degree that their

The specific strength is a material’s strength (force per unit area at failure) divided by its density.It is also known as the strength-to-weight ratio or strength/weight ratio.
