POLYVINYL CHLORIDE COMPOSITION Russian patent published in 2009 - IPC C08L27/06 

FIELD: chemistry.

SUBSTANCE: present invention pertains to hard polyvinyl chloride compositions using filler with plasticising and stabilising effect for making materials, mainly construction materials, and can be used for making moulded profile objects, siding, pipes etc. The polyvinyl chloride composition (PVC composition) contains a plasticiser, calcium stearate and a dispersion polyfunctional filler - a product of recycling oil, with the following ratio of ingredients, in wt pts: PVC composition (in terms of polyvinyl chloride) - 100, oil recycling product - 5-25.

EFFECT: cheaper PVC-based materials, particularly moulded materials, without deterioration of the application properties, increased melt fluidity, increased stability of PVC composition, wider field of using industrial wastes.
