Abstract

Disclosed is a composition that can rapidly plasticize polymers, including, in relation to the total mass of (A) and (B): between 0.1 and 99 mass-% of at least one ester of 1,4:3,6-dianhydrohexitol (A), having a molar mass varying between 255 and 345 g·mol−1 and selected from among monoesters and diesters of isosorbide, isomannide and isoidide; and between 1 and 99.9 mass-% of at least one compound (B) having a molar mass greater than 345 g·mol−1 and selected from among the esters of 1,4:3,6-dianhydrohexitol, the esters of cyclohexane polycarboxylic acid, the esters of phthalic acid, and glycerol esters. Also disclosed is a method for the production of a plasticized object using constituents (A) and (B), as well as to the use of the ester compound (A) as a polymer gelification accelerator.
