Microstructure Development in Polymers.

Abstract

The development of microstructure in strained and in relaxed polymer systems has been studied. Results of crystallization of Nylon 6.6 and polyester fibers shows a competition between amorphous relaxation and the growth of fibrillar crystals. A transformation theory for stress-assisted transformation in terms of a defective thermal dendrite model has been proposed. Preliminary SANS work on PET has been successful. Quiescent crystallization studies of TMPS crystallization have been made and have resulted in a transformation-front description of reversible crystallization during cooling. Research on the adhesion of thermal/compression-bonded polypropylene laminates has shown large roles played by relative laminar orientation and prior heat-treatment. (Author)
