Title
(EN) CYCLOBUTANE-CONTAINING THERMALLY CLEAVABLE POLYMERS
(FR) POLYMÈRES THERMIQUEMENT CLIVABLES CONTENANT DU CYCLOBUTANE
Abstract
(EN)
A polymer is made from polymerization of CBDA monomers. The resulting polymer is thermally cleavable, making it recyclable when heated and degraded. The resulting intermediate material can be hydrolyzed back to initial starting material for synthesizing CBDA monomers.
(FR)
L'invention concerne un polymère obtenu par polymérisation de monomères de CBDA. Le polymère résultant est clivable thermiquement, ce qui le rend recyclable lorsqu'il est chauffé et dégradé. Le matériau intermédiaire résultant peut être hydrolysé pour revenir au matériau de départ initial pour synthétiser des monomères de CBDA.
