Zusammenfassung:	The present invention relates to a method for the preparation of a sulfur-free copolymer comprising at least one alkyl methacrylate and maleic anhydride having a number average molecular weight of 3000 to 9000 g/mol by solution polymerization in the presence of a radical initiator. La présente invention concerne un procédé pour la préparation d'un copolymère exempt de soufre comprenant au moins un méthacrylate d'alkyle et de l'anhydride maléique ayant un poids moléculaire moyen en nombre de 3000 à 9000 g/mol par polymérisation en solution en présence d'un initiateur radicalaire.
