| description | Propylene-based elastomer compositions that include a blend of a majority polymer fraction having a higher Mw and a minority polymer fraction having a lower Mw, methods of making same, and hot melt adhesives including such compositions. The polymer blend compositions can include: a major polymer fraction having a Mw of about 100,000 to about 300,000 and a melt flow rate of about 0.1 g/10 min to about 70.0 g/10 min, according to ASTM D1238; and a minor polymer fraction having a Mw of about 5,000 to about 60,000 and a Brookfield viscosity of about 500 cP to about 50,000 cP, according to ASTM D-3236 (190°C), wherein an amount of the at least one other polyolefin comonomer in the minor polymer fraction is at least 7 wt% less than an amount of the at least one other polyolefin comonomer in the major polymer fraction.
La présente invention concerne des compositions d'élastomères à base de propylène qui comprennent un mélange d'une fraction de polymère majoritaire ayant un Mw supérieur et une fraction de polymère minoritaire ayant un Mw inférieur, leurs procédés de préparation et des adhésifs thermofusibles comprenant de telles compositions. Les compositions de mélanges de polymères peuvent comprendre : une fraction de polymère majoritaire ayant un Mw d'environ 100 000 à environ 300 000 et un indice de fluidité d'environ 0,1 g/10 min à environ 70,0 g/10 min, selon la norme ASTM D1238; et une fraction de polymère minoritaire ayant un Mw d'environ 5 000 à environ 60 000 et une viscosité de Brookfield d'environ 500 cP à environ 50 000 cP, selon la norme ASTM D-3236 (190 °C), une proportion de l'au moins un autre comonomère de polyoléfine dans la fraction de polymère minoritaire étant d'au moins 7 % en poids inférieure à une proportion de l'au moins un autre comonomère de polyoléfine dans la fraction de polymère majoritaire. |
