POLYMER COMPOSITION PREPARATION METHOD Russian patent published in 2006 - IPC C08J3/05 C08L23/12 C08K3/08 C08K13/06

Abstract RU 2277548 C1

FIELD: polymer materials.

SUBSTANCE: invention aims at creating biological protection against radioactive emissions employed in nuclear power plants and provides a method for preparing polymer composition involving operation of mixing tungsten powder, iron powder, and powdered polypropylene. Prior to be mixed, tungsten powder is subjected to mechanical treatment for 3-5 h on ball mixer at weight ratio of metallic balls to tungsten powder between 5:1 and 7:1.

EFFECT: enabled manufacture of part from composition without stratification and imperfections.
