Investigation on the Crystallization Behaviors of Polyoxymethylene with a Small Amount of Ionic Liquid

Investigation on the Crystallization Behaviors of Polyoxymethylene with a Small Amount of Ionic Liquid

Polyoxymethylene (POM) blends with excellent stiffness⁻toughness balance are successfully developed using Tributyl(octyl)phosphonium bis(trifloromethanesulfonyl) imide (TBOP-TFSI), one type of room-temperature ionic liquid, as the nucleating agent. Crystallization behaviors of POM blends h...
