Polymer alloys: science and practice

Abstract

The diversity of applications, versatality of property modifications, motivations for development and commercial significance of polymer alloys are reviewed with reference to commercially available materials. The key steps and scientific considerations central to the development of thermoplastic blend systems are discussed. The scientific considerations in developing the technology, such as thermodynamics of polymer-polymer miscibility, thermal and mechanical compatibility, phase diagram/morphology, interphase adhesion, and kinetics of solidification are highlighted with the help of specific examples from practice. Specific areas for research and development in polymer alloys in India are indicated emphasizing the need for an applied research bias.
