FOAM BASED ON POLYETHYLENE GRAFTED WITH POLYDIMETHYLSILOXANE

摘要

FIELD: chemical industry.;SUBSTANCE: invention relates to foams based on polyethylene grafted with polydimethylsiloxane. Proposed foam containing a polymer matrix containing a polymerized siloxane grafted with polyethylene, where the polymerized siloxane has the formula (II) (II), where: R₁=CH₃ or C₂H₅; R₂=CH₃ or C₂H₅; m = 80–500; and n = 80–500, and many pores formed in the polymer matrix, and containing a foaming agent containing carbon dioxide, where the foam has a porosity of more than 75 %. Method for producing foam is also described.;EFFECT: technical result: obtained foam with a minimum content of impurities with a low attenuation coefficient.;11 cl, 6 tbl
