Title (EN) METHYLATED HYDROXYPROPYLCELLULOSE AND TEMPERATURE RESPONSIVE PRODUCTS MADE THEREFROM
(FR) HYDROXYPROPYLCELLULOSE METHYLEE ET PRODUITS SENSIBLES A LA CHALEUR FABRIQUES AVEC LEDIT COMPOSE
Abstract:
(EN) The present invention is directed to a method of producing methylated hydroxypropylcellulose (m-HPC). By controlling the degree of methylation, one can manipulate the lower critical solution temperature (LCST) of the m-HPC polymer to below room temperature and thereby stabilize the polymer in water above about 30 °C. The present invention is also directed to binder compositions, fibrous substrates, water-dispersible products and thermoformable products containing the m-HPC polymer.
(FR) La présente invention concerne un procédé de production d'hydroxypropylcellulose méthylée (m-HPC). En régulant le degré de méthylation, on peut manipuler la température de solution critique inférieure (LCST) du polymère de m-HPC et l'amener au-dessous de la température ambiante, ce qui permet de stabiliser le polymère dans l'eau au-dessus d'environ 30 °C. La présente invention concerne également des compositions liantes, des substrats fibreux, des produits dispersables dans l'eau et des produits thermoformables contenant le polymère de m-HPC.
