Title (EN) BENZOFURAN-2-ONIC OR INDOLIN-2-ONIC COMPOUNDS AS STABILIZERS OF POLYMERS
(FR) COMPOSES BENZOFURAN-2-ONIQUES OU INDOLIN-2-ONIQUES EN TANT QUE STABILISATEURS DE POLYMERES
Abstract: front page image
(EN)They are used as antioxidizing of organic polymers benzofuran-2-onic and/or indolin-2-onic compounds which present in the position 3, either at least one hydrogen atom, or an organic remains bound by a double binding to the rest of the molecule, and/or optionally substituted bis-3-benzofuran-2-onic compounds and/or optionally substituted bis-3-indolin-2-onic compounds. These compounds having the following characteristics: (i) The benzofuran-2(3H)-onic compounds unsubstituted in the position 3 having in the position 5 no hydroxyl esterically inhibited by a tert. butyl group; (ii) the indolin-2-onic compounds, in as much as in these compounds the nitrogen atom (1-) is bound to a hydrogen atom or to an alkyl or aralkyl group and only the position 3 has an additional substituent, wherein this additional substituent has no acetamidic structure; (iii) the polymer organic material being substantially free of halogen when 3- acyl-benzofuran-2-onic compounds are used. The invention relates also to polymer materials stabilized in this manner. New benzofuran-2-onic and indolin-2-onic compounds are disclosed which present in the molecule thereof at least two benzofuran-2-onic and indolin-2-onic cores; These cores are connected either directly in their position 5, or bridged by means of an organic remains in position 3-. 5- or 7.
(FR)L"on utilise comme antioxydants de polymeres organiques des composes benzofuran-2-oniques et/ou indolin-2-oniques qui eux presentent en position 3, ou bien au moins un atome d"hydrogene, ou bien un reste organique lie par une double liaison au restant de la molecule, et/ou des composes eventuellement substitues bis-3-indolin-2-onique et/ou des composes eventuellement substitues bis-3-indolin-2-oniques. Ces composes, avec les considerants suivants: (i) les composes benzofuran-2(3H)-oniques non-substitues en position 3 ne presentant en position 5 aucun hydroxyle inhibe steriquement par un groupe butyle tert., (ii) les composes indolin-2-oniques, pour autant que dans ces composes l"atome d"azote (1-) soit lie a un atome d"hydrogene ou a un groupe alkyle ou aralkyle et qu"uniquement la position 3 porte un substituant supplementaire, dans lesquels ce substituant supplementaire ne presentant pas de structure acetamidique et (iii) le materiel organique polymere etant essentiellement libre d"halogene lorsque l"on utilise des composes 3-acyle-benzofuran-2-oniques. L"invention concerne egalement les materiaux polymeres stabilises de cette maniere. Il est decrit de plus de nouveaux composes benzofuran-2-oniques et indolin-2-oniques, qui presentent dans leur molecule au moins deux noyaux benzofuran-2-oniques et indolin-2-oniques; ces noyaux etant relies soit directement en leur position 5, soit pontes par l"intermediaire d"un reste organique en position 3-. 5- ou 7.
