METHOD OF PREPARING CELLULOSE-CONTAINING POLYMER SUPER-CONCENTRATE AND COMPOSITE MATERIALS BASED ON SAID SUPER-CONCENTRATE Russian patent published in 2011 - IPC C08L97/00 C08L97/02 

FIELD: chemistry.

SUBSTANCE: method involves plastification with extrusion of dispersion components, and specifically cellulose filler and thermoplastic polymer matrix. The thermoplastic polymer matrix consists of high-density polyethylene, a compatibiliser in form of graft polyolefin and a lubricant. The lubricant used is pre-ozonised polyethylene homologues in form of super-molecular polyethylene, low-density linear polyethylene and ethylene vinylacetate in ratio of 1:3:5. The graft polyolefin used in the compatibiliser is high-density polyethylene to whose molecular structure glycidyl methacrylate is grafted. Use of such a compatibiliser increases energy compatibility of dispersion components used in preparing a cellulose-containing polymer super-concentrate. The composite material contains a polymer and a super-concentrate with 30-70 wt % content of the super-concentrate.

EFFECT: composite materials based on the obtained cellulose-containing polymer super-concentrate have good physical and mechanical characteristics, namely strength and water resistance.
