FIELD: chemistry.
SUBSTANCE: invention relates to plasticised polyvinyl chloride compositions containing plasticisers, particularly polyvinyl chloride plastisols, as well as use of C9-C11 alkylbenzoate as a plasticiser in a flooring polyvinyl chloride composition which contains polyvinyl chloride and 20-200 pts. wt plasticiser per 100 pts. wt polyvinyl chloride in order to reduce overall content of plasticiser in the composition compared to main plasticisers. The polyvinyl chloride composition for use in making anti-stain upper layers of floors contains polyvinyl chloride, C9-C11 alkylbenzoate, a plasticiser different from C9-C11 alkylbenzoate and can additionally contain a stabiliser. The polyvinyl chloride composition for use in making glass ingrained textile floor layers with thick fleece contains polyvinyl chloride, C9-C11 alkylbenzoate, a plasticiser different from C9-C11 alkylbenzoate, a stabiliser and filler. The polyvinyl chloride composition for use in making decorative foamed floor layers contains polyvinyl chloride, C9-C11 alkylbenzoate, a plasticiser different from C9-C11 alkylbenzoate, a blowing agent and can additionally contain a TiO2 stabiliser. The polyvinyl chloride composition for use in making layers of foamed floor lining contains polyvinyl chloride, C9-C11 alkylbenzoate, a plasticiser different from C9-C11 alkylbenzoate, a blowing agent and can additionally contain a TiO2 stabiliser. Said polyvinyl chloride compositions contain a plasticiser different from C9-C11 alkylbenzoate which is selected from a group comprising di-2-ethylhexylphthalate, diisononylphthalate, di-2-propylheptylphthalate, diisodecylphthalate, di-2-ethylhexylterephthalate and mixtures thereof.
EFFECT: use of C9-C11 alkylbenzoates enables to obtain low-viscosity low-volatile plasticisers which melt fast with low gel point on a hot stand and which can be used to prevent formation of stains, related with use of di-2-ethylhexylphthalate and diisononylphthalate; low viscosity of C9-C11 alkylbenzoates enables to prepare solvent-free flexible polyvinyl chloride compositions which satisfy volatile organic compound (VOC) strict constraints.
