A substantially zero-carbon-emission (ZCE) process for making propylene polymers and copolymers including: converting alkanes to the olefin monomers ethylene, propylene, and butene or combinations thereof, using renewable electric power and scrubbing the stack gases from any fired heaters or boilers to remove carbon dioxide, in an oxidative-coupling of methane plant including the steps of passing alkanes through an ethylene plant while adding oxygen, passing a portion of the polymerization grade ethylene through a 2-butene plant, and passing the 2-butene stream and a portion of the polymerization grade ethylene stream through a propylene plant. The polymerization grade propylene is polymerized to produce isotactic homopolymer polypropylene, or ethylene-propylene random copolymer, or impact grade polypropylene containing ethylene-propylene rubber.

Integrated process for producing propylene polymers and copolymers with reduced greenhouse gas emission

A product made by a substantially zero carbon emission process for making amorphous poly alpha olefins including, converting alkanes to olefin monomers ethylene, propylene, and 1-butene or combinations thereof using renewable electric power in an oxidative-coupling of methane plant including the steps of passing alkanes through an ethylene plant while adding oxygen, passing the first polymerization grade ethylene through a 2-butene plant, passing a first of the two 2-butene streams and one of the polymerization grade ethylene through a propylene plant, and passing a second of the two 2-butene streams through a 1-butene plant. The next step in the process for making amorphous poly alpha olefins includes polymerizing at least one of the polymerization grade alkenes which includes applying a temperature of 130 degrees Fahrenheit to 175 degrees Fahrenheit to at least one of the polymerization grade alkenes and scrubbing at least one boiler stack gases.

Integrated product by process for poly olefin production with reduced greenhouse gas emission

Adding a compatible high melt flow rate (MFR), low melt viscosity, hydrogenated styrene block copolymer to amorphous poly alpha-olefins (APAOs) results in adhesives that show acceptably high elongation and tensile strength, and which, when applied by different hot melt application methods onto elastic strands, result in personal hygiene article components that perform comparably to such components assembled using just styrene block copolymer components formulated with compatible tackifiers, processing oils and other additives.

Performance APAO hot melt adhesives containing high melt flow rate hydrogenated styrene block copolymers

Adding a low molecular weight (or alternatively, high melt flow rate), functionalized, isotactic polypropylene (iPP) to a hot melt adhesive (HMA), composition containing a propylene-butene-1, and/or a propylene-ethylene amorphous poly alpha olefin (APAO) copolymer, in addition to other co-adjuvants (such as a tackifier or a plasticizer), results in an APAO-based HMA that shows improved tensile strength and bonding properties, over an HMA that contains only the propylene-butene-1 and/or the propylene-ethylene APAO copolymer (with or without a tackifier and/or a plasticizer).
