Abstract
Amorphous propylene-ethylene copolymers are described herein that can include high amounts of ethylene and exhibit desirable softening points and needle penetrations. The desirable combinations of softening points and needle penetrations in these propylene-ethylene copolymers allow them to have a broad operating window. Due their broad operating window, the propylene-ethylene copolymers can be utilized in a wide array of applications and products, including hot melt adhesives.
Claims20
An adhesive comprising at least one propylene-ethylene copolymer and at least one high propylene-content polymer, wherein said propylene-ethylene copolymer comprises at least 10 weight percent of ethylene and a softening point of at least 99° C.
An adhesive comprising a propylene-ethylene copolymer and a high propylene-content polymer, wherein said propylene-ethylene copolymer comprises a polydispersity of at least 3.
