POLYMER COMPOSITION Russian patent published in 2005 - IPC

FIELD: polymer materials.

SUBSTANCE: invention relates to creation plasticized compositions based on suspension polyvinylchloride, which are used in manufacturing film materials, in particular polyvinylchloride insulation tape. Composition contains suspension polyvinylchloride, dioctyl phthalate plasticizer, lead(III) sulfate, calcium stearate lubricant, carbon black, mixture of chlorinated C10-C30-hydrocarbons with 40-50% Cl content as secondary plasticizer, and residue of vacuum distillation of cobalt-freed still residue obtained in rectification of propylene hydroformylation product with boiling range 300-310°C.

EFFECT: improved quality of insulation tape, reduced production expenses, and enabled partial utilization of waste.
