What makes synthetic polymers so useful Synthetic polymers are so useful Synthetic polymers are plastics They are useful because they can be recycled they are cheap they are light and strong . 151977 Melting Behavior of Alipha tic and Aroma tic Diamides INTRODUCTION Aromatic polyamides form a special class of polymers which have high melting temperatures and yield fibers with very high Youngs moduli3 The melting behavior of aliphatic alip Hypothesis:.
