Adhesive Compositions Made from Propylene-Based Polymers and Crystalline C2/C3 Homopolymer |
摘要 |
The present invention is related to adhesive composition, having a polymer blend comprising a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin, and a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin; wherein the second propylene-based polymer is different than the first propylene-based polymer; wherein the polymer blend has a melt viscosity, measured at 190° C. and determined according to ASTM D-3236, of about 1,000 cP to about 5,000 cP; a propylene polymer; and wherein the adhesive composition is substantially free of a functionalized polyolefin, wherein the functionalized polyolefin is selected from at least one of a maleic anhydride-modified polypropylene and a maleic anhydride-modified polypropylene wax. |

1. An adhesive composition comprising:
a polymer blend comprising a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin, and a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin; wherein the second propylene-based polymer is different than the first propylene-based polymer; wherein the polymer blend has a melt viscosity, measured at 190° C. and determined according to ASTM D-3236, of about 1,000 cP to about 5,000 cP; a propylene polymer; and wherein the adhesive composition is substantially free of a functionalized polyolefin, wherein the functionalized polyolefin is selected from at least one of a maleic anhydride-modified polypropylene and a maleic anhydride-modified polypropylene wax. |
