Publication number: 20240043589Abstract: Propylene-ethylene copolymers are provided that exhibit superior tensile strength and mechanical properties due to their specific propylene and ethylene content, triad tacticity, viscosity, and crystallinity. Moreover, we have discovered that certain processing conditions, such as polymerization temperature and external donor to catalyst ratios, can facilitate the production of the high tensile strength propylene-ethylene copolymers described herein. Furthermore, the high tensile strength propylene-ethylene copolymers may be used to produce a variety of hot melt adhesives, such as those for hygiene applications, woodworking applications, lamination applications, and packaging applications, which exhibit unique and superior mechanical properties.Type: ApplicationFiled: July 26, 2022Publication date: February 8, 2024Inventors: Jianning Liu, Marc Stacey Somers, Bennett Haines Novak, Raymond Prescott Cottle, Bee Kim Liew, Andrea Gail Hagood, Terri Roxanne Carvagno
