Summary:An adhesive composition comprising a copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and C4-20 ???-olefins, the copolymer having (i) a content of units derived from propylene of greater than about 50 mole percent, (ii) a Brookfield viscosity at 190C from about 50 to about 100,000 cP, (iii) an MWD from about 1.5 to about 15, and (iv) containing less than about 50 ppm residual catalyst metal. Una composicion de adhesivo que comprende un copolimero de propileno y por lo menos un comonomero seleccionado del grupo que consiste de etileno y a-olefinas de 4 a 20 atomos de carbono, el copolimero que tiene (i) un contenido de unidades derivadas de propileno mayor que aproximadamente 50 por ciento en mol, (ii) una viscosidad Brookfield a 190 C desde aproximadamente 50 hasta aproximadamente 100,000 cP, (iii) una MWD desde aproximadamente 1.5 hasta aproximadamente 15, y (iv) que contiene menos que aproximadamente 50 ppm de metal de catalizador residual.
