FIELD: chemistry.
SUBSTANCE: thermoplastic plasticised modified cellulose acetate consists of cellulose acetate, a low-molecular plasticiser, a stabiliser, a reactive modifying agent-oligoether diisocyanate. As the oligoether diisocyanate, the reaction product of polyethylene-polybutylene glycol adipate with a molecular weight of 1500-2500 with MDI is used at a molar ratio of oligoether diisocyanate to cellulose acetate equal to (1:0.4 to 1:4). In a particular embodiment of the invention, the thermoplastic plasticized modified cellulose acetate contains dyes and fillers. The invention also relates to a process for the production of thermoplastic plasticised modified cellulose acetate, which is carried out in a single rotary-type mixer at a temperature of 155-165°C.
EFFECT: increasing physicomechanical and thermophysical properties of products based on thermoplastic plasticised modified cellulose acetate, which are preserved during their long-term operation.
