Method for synthesizing alkoxypolyalkylene glycol (meth)acrylates by transesterification |
| abstract |
The invention relates to a method for synthesizing alkoxypolyalkylene glycol (meth)acrylic esters by means of a transesterification reaction between a light alkyl (meth)acrylate and an alkoxypolyalkylene glycol in the presence of a catalyst chosen from the list comprising zirconium acetylacetonates, lithium acetylacetonates, calcium acetylacetonates, dibutyltin oxide, distannoxanes and caesium carbonate, used alone or as a mixture. This method is advantageously used to prepare methoxypolyethylene glycol methacrylates (MPEGMA) having a molar mass ranging from approximately 500 to approximately 5000. |
