Title (EN) ALPHA-METHYLSTYRENE DIMER DERIVATIVES
(FR) DERIVES DE DIMERES DE L'ALPHA-METHYLSTYRENE
Abstract: front page image
(EN)The present invention relates to a method of making alpha-methylstyrene dimers by combining a cobalt catalyst, a free-radical initiator and an alpha-methylstyrene monomer, in an inert atmosphere, to form a mixture. The mixture is heated to a temperature in the range of 65 °C to 140 °C to form alpha methyl styrene dimers. The present invention also relates to the products produced by this inventive method.
(FR)L'invention concerne un procédé qui permet de fabriquer des dimères d'alpha-méthylstyrène en combinant un catalyseur à base de cobalt, un initiateur de polymérisation radicalaire et un monomère d'alpha-méthylstyrène, dans une atmosphère inerte, de façon à former un mélange. On chauffe ledit mélange à une température comprise entre 65 et 140 °C afin de former des dimères d'alpha-méthylstyrène. L'invention concerne également les produits fabriqués selon le procédé de l'invention.
