METHOD OF PREPARING POLYMER COMPOSITION

摘要

FIELD: polymer materials. SUBSTANCE: composition is prepared by mixing for 1-2 h polypropylene or polyethylene with boron nitride filler at weight ratio from 1:2 to 1:1 in ball mixer at weight ratio of metal balls to composition being stirred 4:1 followed by adding the rest of olefin polymer and resuming stirring in ball mixer for further 0.5-1 h. Resulting composition is suitable for manufacture of construction parts for biological protection against neutron emissions. EFFECT: enabled preparing polymer compositions for manufacturing defect-free items. 1 tbl, 10 ex
