ACTIVE PRINCIPLE FORMATION INITIATOR COMPOSITION CONTAINING SORBITOL DIACETATE AND SORBITOL TRIACETAL

摘要

FIELD: chemistry.;SUBSTANCE: present invention relates to an active center formation initiator composition, a method for preparing an active center formation initiator composition, versions of using the active center formation initiator composition, the polymer composition and a method of producing the improved polymer. Said active principle formation initiator composition contains a compound of formula (I), a compound of formula (II), compound of formula (III) and compound of formula (IV):; ;Weight ratio of compound of formula (I), weight of compound of formula (II) and combined weight of compounds of formula (III) and formula (IV) is equal to (97.00–99.90):(0.20–8.00):(0.02–1.00). Composition of initiator of formation of active centers is used in producing a polymer with improved transparency and low extrusion temperature. Effect of different concentrations of sorbitol triacetal and sorbitol acetal in a composition of an initiator of formation of active centers on different formation of active centers of polymers.;EFFECT: technical result is the development of a composition of an initiator for formation of active centers, containing certain amounts of sorbitol acetal, sorbitol diacetal and sorbitol triacetate.;16 cl, 2 tbl, 6 ex
