摘要： A continuous extrusion process for the functionalization of polymers through reactive extrusion. The process uses a continuous extrusion reactor comprising at least two sequential, very closely-coupled, independently driven screw extruders having a total effective length to diameter ratio greater than 60 to 1 and as high as 112 to 1 and providing greatly extended reaction times for efficiently producing a grafted polymer having a high level of functionalization. Drying of the polymer feed is performed in the continuous extrusion reactor. Multiple injections of reactants may be provided. Shear modification of the molecular weight of the grafted polymer is performed in the continuous extrusion reactor after the functionalization reactions. A continuous extrusion reactor and a grafted polymer having a high level of functionalization are also disclosed.

摘要： 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.

摘要： A low viscosity, high tensile strength polymer having a bi-modal molecular weight distribution is produced using a combination of high molecular weight polymer and low molecular weight polymer. The polymer chains have a high content of meso dyads that results in a greater amount of crystalline regions when the polymer is solidified. The low molecular weight chains provide high flow characteristics when the polymer is molten. The process for producing the high content of meso dyads includes the use of an external donor catalyst during the reaction.
