Carbamate End-capped Polyoxymethylene Copolymer with Enhanced Thermal Stability Prepared by Reactive Extrusion
Polyoxymethylene (POM), also known as polyacetal, is an important engineering plastic with
high crystallinity. While POM is inherently unstable with the existence of hemiformal chain ends,
they undergo depolymerization easily. Therefore, seeking for ways of stabilization is crucial to
researchers. Herein, we present a new method involving an end-capping agent and the process of
extrusion to ach...
