METHOD FOR PRODUCTION OF ULTRAHIGH MOLECULAR POLYETHYLENE COMPOSITION WITH POLYSILOXANE THAT HAS MEMORY EFFECT

摘要

FIELD: technological processes. ^ SUBSTANCE: method includes mixing of ultrahigh molecular polyethylene with polysiloxane in mechanical mixer at controlled value of deformation energy density. Mixing of components is realised at concentration of ultrahigh molecular polyethylene of 20-35 wt % and performed in the range of deformation energy densities selected depending on ratio of components determined according to formula taugamma=[(8/10).(ϕ-0.2)].105, where taugamma is density of deformation energy, kJ/m3, ϕ is fraction of ultrahigh molecular polyethylene in mixture. ^ EFFECT: compositions possess memory effect, heat-shrinkage properties. ^ 5 tbl, 5 ex
