FIELD: chemistry.
SUBSTANCE: invention relates to production of polymer compositions based on polyvinyl chloride (PVC) and reactive oligomer for making profiled-trim moulding articles. Polymer composition based on polyvinyl chloride S7058M contains complex heat stabiliser, impact strength modifier FM-22, stabilizer-lubricant calcium stearate and as a reactive oligomer - poly-isocyanate Lupranate M20S.
EFFECT: invention simplifies the technology of producing polymer composition with higher heat resistance and processability.
