Abstract

Characterization studies of reaction injection moulded (RIM) processed (in-situ polymerized) polyester-based segmented thermoplastic polyurethane have been performed utilizing various morphological techniques. The fast and exothermic urethane polymerization results in large temperature gradients in the mould which influence molecular weight and morphological structures. The present work is conducted to draw relationships between sample morphology and the processing conditions utilized to form the polymer.
