FIELD: chemistry.
SUBSTANCE: present invention relates to a composition for producing a plasticiser, as well as a composition for producing a resin product. Said composition for producing a plasticiser contains a tetraester-based composition which contains one or more tetraesters of formula
in which R1-R4 independently represent an n-pentyl group, a branched pentyl group or a cyclopentyl group, wherein the alkyl groups of the tetraester are obtained from a mixture consisting of an isomeric mixture of hexanoic acid and cyclopentylmethanoic acid. Composition for producing resinous product contains 100 wt.pts. resin and from 5 to 150 wt.pts. plasticizer composition.
EFFECT: plasticiser composition retains the same or improved plasticisation efficiency and absorption rate compared to the use of a conventional plasticiser, and also markedly improves mechanical properties, resistance to migration, migration under stress and characteristics of losses.
