Title
(EN) SILYL DERIVATIVES OF 2,6-DIMETHYL-4-ALLYL PHENOL
(FR) DERIVES SILYLE DE PHENOL 2,6-DIMETHYL-4-ALLYLE
Abstract
(EN)
Silyl derivatives of 2,6-dimethyl-4-allyl phenol include compositions of formula (I), where R1, R2, and R3 are independently selected from alkyl and phenyl groups having up to about eight carbon atoms and/or are connected to form one or more rings. They may be made by silylating the corresponding hydroxyl compound. They are useful as comonomers for olefins to introduce functional sites in high molecular weight copolymers.
(FR)
L'invention se rapporte à des dérivés silyle de phénol 2,6-diméthyle-4-allyle, qui contiennent des compositions représentées par la formule (I), où R1, R2, R3 sont séparément choisis parmi des groupes alkyle et phényle comportant jusqu'à environ 8 atomes de carbone et/ou sont reliés pour former une ou plusieurs chaînes fermées. Ces dérivés peuvent être obtenus par silylation du composé hydroxyle correspondant. Ils sont utiles comme comonomères pour oléfines, en vue de l'introduction de sites fonctionnels dans des copolymères à poids moléculaire élevé.
