POLYVINYL CHLORIDE COMPOSITION FOR PRODUCING FILM MATERIALS Russian patent published in 2011 - IPC C08L27/06 C08K13/02 C08J3/18 

FIELD: chemistry.

SUBSTANCE: polyvinyl chloride composition for producing film materials contains suspended polyvinyl chloride, a mixture of plasticisers di-(2-ethylhexyl)phthalate, di-(2-ethylhexyl) sebacate, a complex metal-containing stabiliser - complex Ba-Zn stabiliser, filler - chalk, titanium dioxide, cellulose, lubricant - calcium stearate, pigments, polymer modifier - copolymer of vinyl chloride and vinyl acetate (VA-5) and a mixture of an oligomeric plasticiser based on a mixture of adipic or phthalic esters, n-butyl alcohol, 2-ethylhexanol and polypropylene glycol - component A with a surfactant which contains oxyethylated monoalkylphenol based on trimers of propylene - component B in ratio A:B equal to (11.5-18.23):1.

EFFECT: film material has low stickiness and hardness, high resistance to heat-and-light ageing while preserving physical and mechanical properties.
