Abstract

L'invention concerne de nouveaux esters de l'acide phosphoreux et de l'acide phosphorique. Ce sont le phosphite de bis(5-norbornène-2-méthyle), le phosphite de tris(5-norbornène-2-méthyle) et le phosphate de tris(5-norbornène-2-méthyle). Ajoutés à des homopolymères ou à des copolymères du chloroprène, à des copolymères d'isobutylène et d'isoprène chlorés ou encore à des mélanges de ces matières avec un copolymère styrène/butadiène ou avec du caoutchouc naturel, ces esters améliorent la résistance à l'ozone des produits vulcanisés, ainsi que la résistance à la flexion des copolymères de chloroprène et de soufre ou de leurs mélanges avec un copolymère styrène/butadiène ou avec du caoutchouc naturel.The invention relates to novel esters of phosphorous acid and phosphoric acid. These are bis (5-norbornene-2-methyl) phosphite, tris (5-norbornene-2-methyl) phosphite and tris (5-norbornene-2-methyl) phosphate. Added to homopolymers or to copolymers of chloroprene, to copolymers of chlorinated isobutylene and isoprene or to mixtures of these materials with a styrene / butadiene copolymer or with natural rubber, these esters improve resistance to water. ozone of vulcanized products, as well as the flexural strength of copolymers of chloroprene and sulfur or of their blends with a styrene / butadiene copolymer or with natural rubber.
