| description | L'invention concerne un procédé de polymérisation anionique utilisant un amorceur à base d'amidure alcalin, ainsi que les polymères obtenus par ce procédé. Le procédé de polymérisation selon l'invention est caractérisé en ce qu'on utilise un amorceur qui résulte de l'association d'un amidure alcalin choisi dans le group formé par l'amidure de sodium, l'amidure de potassiumou l'amidure de lithium et d'un sel alcalin dont le cation est choisi dans le groupe formé par le potassium, le lithium ou le sodium, l'anion étant choisi dans le groupe formé par les anions thiocyanate, nitrite, cyanure et cyanate. Ces amorceurs permettent de procéder à la polymérisation anionique des monomères vinyliques, hétérocycliques et dieniques, en vue de l'obtention de polymères spéciaux ou de grande diffusion, avec une grande souplesse et dans des conditions économiquies avantageuses.
The invention relates to an anionic polymerization process using an initiator based on an alkali metal amide in combination with an alkali metal salt, as well as to the polymers obtained by this process. The polymerization process according to the invention is characterized in that an initiator is used which results from the combination of an alkali metal amide selected from the group comprising sodium amide, potassium amide or lithium amide and an alkali metal salt of which the cation is selected from the group comprising potassium, lithium or sodium, the anion being selected from the group comprising the thiocyanate, nitrite, cyanide and cyanate anions. These initiators make it possible to carry out the anionic polymerization or vinyl, heterocyclic and diene monomers in order to obtain special polymers or widely used polymers, with great adaptability and under advantageous economic conditions. |
