MOULDING MATERIAL MADE FROM VINYL CHLORIDE POLYMER OR POLYVINYL CHLORIDE, FILM MADE FROM SAID MOULDING MATERIAL AND METHOD OF MAKING FILM OR FILM CLOTH Russian patent published in 2010 - IPC C08L27/06 C08J5/18 C08L67/02 

FIELD: chemistry.

SUBSTANCE: invention relates to moulding composition for making films from vinyl chloride polymer or polyvinyl chloride in amount of 5-94 wt % and with coefficient K ranging from 50 to 90, an additive in amount of 2-25 wt % and a polymer based on polycrystalline or amorphous polyester with crystallisation half-time in molten state at least equal/longer than 5 minutes, where weight percentages are calculated per total weight of the moulding material, and the moulding material is a mixture of vinyl chloride polymer or polyvinyl chloride and polyester as a drawing capacity modifier and amount of polyester ranges from 5 to 90 wt % of the moulding material. The film is made from the moulding material, which is plasticised, molten and rolled or extruded into a film with thickness ranging from 100 mcm to 1 mm and, if necessary, drawn using a flow line method and/or independently. Drawing ratio ranges from 1.3 to 7, particularly from 3 to 4.

EFFECT: obtained film has improved light transmission, light- and thermal stability, is capable of stretching.
