Définitions

anglais

solid-state polymerization: Reaction of the active end-groups within a solid polymer. It may be intentional as in heating and drying nylon 66 to increase the final degree of polymerization; or it may be undesirable such as that which occurs in fibers under high-temperature conditions in tires that leads to increased degree of polymerization, cross-linking, and subsequent brittleness and loss of strength.
