Title (EN) METHOD OF PREPARING CARBAMATE-FUNCTIONAL POLYMERS
(FR) PROCEDE DE PREPARATION DE POLYMERES A FONCTION CARBAMATE
Abstract: front page image
(EN)A method of preparing a carbamate-functional polymer comprising the steps of providing a hydroxy-functional polymer and reacting a carbamate compound with the hydroxy-functional polymer in the presence of a transcarbamation catalyst, thereby forming a carbamate-functional polymer. The transcarbamation catalyst may be Bi(III) compounds, ZR(IV) compounds, or mixtures of these.
(FR)Cette invention se rapporte à un procédé de préparation d'un polymère à fonction carbamate, qui consiste à former un polymère à fonction hydroxy et à faire réagir un composé de carbamate avec ce polymère à fonction hydroxy en présence d'un catalyseur de transcarbamation, produisant ainsi un polymère à fonction carbamate. Le catalyseur de transcarbamation peut être constitué par des composés Bi(III), des composés Zr(IV) ou des mélanges de ceux-ci.
