Title (EN) METHOD FOR THE SYNTHESIS OF OLIGOMERS OF ACRYLIC ACID
(FR) PROCEDE DE SYNTHESE D'OLIGOMERES D'ACIDE ACRYLIQUE
Abstract:
(EN) The invention relates to a method for the synthesis of an oligomer of acrylic acid represented by the formula (I) in which n is a whole number from 1 to 10, characterised in that it comprises heating acrylic acid to a temperature of between 50°C and 200°C in the presence of a catalyst, water, and at least one polymerisation inhibitor. The formula (I) in which n is equal to 0 represents acrylic acid, the precursor for preparing the oligomer of acrylic acid.
(FR) L'invention a donc pour objet un procédé de synthèse d'un oligomère d'acide acrylique représenté par la formule (I): dans laquelle n est un entier allant de 1 à 10, caractérisé en ce qu'il comprend le chauffage d'acide acrylique à une température allant de 50°C à 200°C en présence d'un catalyseur, d'eau, et d'au moins un inhibiteur de polymérisation. La formule (I) dans laquelle n=0 représente l'acide acrylique, précurseur pour préparer l'oligomère d'acide acrylique.
