Title
(EN) GAMMA RADIATION STERILIZABLE ACRYLIC POLYMER
(FR) POLYMERES ACRYLIQUES POUVANT ETRE STERILISES PAR RAYONS GAMMA
Abstract
(EN)
Provided are methyl methacrylate polymers admixed with a particular additive or additive combination, which show good chemical resistance, as well as maintenance of optical properties and minimal yellowing on exposure to sterilizing gamma radiation.
(FR)
Polymères de méthacrylate de méthyle mélangés à un additif particulier ou à une combinaison additive particulière, et présentant une bonne résistance aux attaques chimiques et un jaunissement minimal, tout en conservant leurs propriétés optiques, lorsqu'ils sont exposés à un rayonnement gamma stérilisant.
