Plasticization of Cellulose Nitrate by 4-Nitrophtalic Acid Esters

Аннотация

The rheological properties of nitrocellulose solutions in cyclohexanone in the presence of phthalic and 4-nitrophthalic diester plasticizers were studied by rotational viscometry to reveal a behavior similar to that of Newtonian fluids. The activation parameters of the viscous flow regime were calculated. An influence of nitroplasticizers and dibutyl phthalate on the rheology of nitrocellulose was established. The influence of plasticizers on the mechanical properties of nitrocellulose films was discussed.
