    Abstract: A product made by 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.

    Abstract: A continuous process for pre-contacting coordination polymerization catalyst components with each other before they are introduced into a polymerization reactor at 130 degrees Fahrenheit to 200 degrees Fahrenheit, where the activated coordination catalyst is contacted with at least one monomer to produce amorphous poly alpha olefin (APAO), the process involving blending a Ziegler-Natta pro-catalyst with a liquid carrier forming a Ziegler-Natta pro-catalyst slurry and flowing a co-catalyst mixture into the Ziegler-Natta pro-catalyst slurry continuously in a pre-contacting device, forming an activated Ziegler-Natta catalyst; continuously injecting the activated Ziegler-Natta catalyst into the heated polymerization reactor while simultaneously, and continuously, injecting propylene monomer and any other alpha-olefin monomers, and hydrogen gas for molecular weight control, initiating an exothermic reaction forming a monomer-polymer-catalyst slurry then continuously stirring the monomer-polymer-catalyst slurry forming an amorphous poly alpha olefin with a saturated backbone.

    Abstract: 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.

    Abstract: 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).
