(EN) SOLUTION BLENDING PROCESS FOR PREPARING THERMOPLASTIC VULCANIZATES
(FR) PROCÉDÉ DE MÉLANGE DE SOLUTION DESTINÉ À PRÉPARER DES VULCANISATS THERMOPLASTIQUES
Abstract
(EN)
This invention relates to the preparation of thermoplastic vulcanizates (TPVs) with unique morphological features, more specifically, this invention relates to a method for preparing TPV compositions wherein the mixing of plastomers and elastomers are carried out in solvent with curatives to induce cross-linking.
(FR)
La présente invention concerne la préparation de vulcanisats thermoplastiques (TPV) présentant des caractéristiques morphologiques uniques. Cette invention porte plus particulièrement sur un procédé de préparation de compositions de TPV, au cours duquel le mélange de plastomères et d'élastomères est effectué dans un solvant contenant des agents de vulcanisation en vue d'induire une réticulation.
