A METHOD FOR CELLULOSE ACETO BUTYRATE MODIFICATION

摘要

The purpose of the invention is development of a method for modification of ABC and preparation of product with predicted dielectric, thermal dynamic and thermal mechanical properties. The set purpose is achieved by that according to the method of cellulose aceto butyrale modification with urethane-containing compounds, in accordance with the proposed invention, as urethane-containing compounds polyurethane at a ratio of ABC:PU between 1:0.01 and 1:0.10 is taken, and thereafter it is subjected to the action of constant magnetic field of an intensity of (2-8)*105 A/m at the temperature of (130-150) DEGREE C.
