A method of recycling a cocatalyst for olefin polymerization is provided. In the method, olefinic monomers are polymerized by using a supported catalyst and a cocatalyst. The supported catalyst is prepared by covalent-bonding a catalyst with a support and the cocatalyst is dissolved in a suspension. The cocatalyst is separated from the resulting suspension after polymerization. The separated cocatalyst is reused for the subsequent polymerization.
L'invention concerne un procédé de recyclage d'un co-catalyseur de polymérisation d'oléfines. Dans le procédé, des monomères oléfiniques sont polymérisés à l'aide d'un catalyseur sur support et d'un co-catalyseur. Le catalyseur sur support est préparé par liaison covalente d'un catalyseur avec un support et le co-catalyseur est dissous dans une suspension. Le co-catalyseur est séparé de la suspension résultante après polymérisation. Le co-catalyseur séparé est réutilisé pour la polymérisation ultérieure.
