Title
(EN) ENGINEERED OLEFINIC COMPOSITIONS
(FR) COMPOSITIONS D'OLEFINES OBTENUES PAR TRANSFORMATION CHIMIQUE
Abstract
(EN)
Thermoplastic olefinic, polymer blends which have superior physical properties and adherence for coating materials such as paints are disclosed. The blends may be formed from various combinations of thermoplastic components such as homopolymers of propylene having an isotactic index which is greater than about 0.93, and/or a crystallinity which is greater than about 56 %, and sequentially polymerized blends of polypropylene and ethylene-propylene copolymers, with elastomeric components such as copolymers of ethylene and butene produced with metallocene or Kaminsky catalysts, and copolymers of ethylene and octene produced with metallocene or Kaminsky catalysts. If desired, other components, such as copolymers of ethylene with C3-C15 alpha olefins or fillers, can be included.

La présente invention concerne des mélanges de polymères d'oléfines thermoplastiques présentant des propriétés physiques supérieures et des propriétés d'adhérence convenant à des substances de revêtement tels que les peintures. Les mélanges peuvent être constitués, d'une part à partir de diverses combinaisons de composants thermoplastiques (tels que les homopolymères de propylène dont l'indice isotactique est supérieur à environ 0,93, et/ou dont la cristallinité est supérieure à environ 56%), d'autre part à partir de mélanges à polymérisation séquentielle de polypropylène et de copolymères d'éthylène-propylène avec des composants élastomères (tels que les copolymères d'éthylène et de butène obtenus grâce à des catalyseurs métallocènes ou de Kaminsky), et enfin à partir de copolymères d'éthylène et d'octène obtenus grâce à des catalyseurs métallocènes ou de Kaminsky. Le cas échéant, il est possible d'inclure d'autres composants tels que des copolymères d'éthylène portant des oléfines alpha en C3-C15 ou des charges.
