Patent number: 10968296Abstract: The invention relates to the use of low levels of aliphatic primary and secondary amines to control air void formation in any polymerization reaction having carbonyl groups, and especially carboxylic acid ester group-containing monomers at a level of at least 10% of total monomer, where the monomer has a peak polymerization exotherm temperature of greater than the boiling point of the monomer. The primary or secondary amines are used in the polymerization mixture at levels of 100 to 5000 ppm, based on the carboxylic acid ester group-containing monomer. It is believed the primary and secondary amines hydrogen bond with the —C?O)O— containing monomer to increase the monomer boiling point, and decrease or even eliminate the formation of air voids due to monomer boiling. The invention is especially useful in polymerization of methymethacrylate polymers and copolymers, either neat, or as a polymer composite system.Type: GrantFiled: December 13, 2017Date of Patent: April 6, 2021Assignee: Arkema FranceInventors: Alaaeddin Alsbaiee, Evan Crocker, Dana Lee Swan

Patent number: 10968297Abstract: Catalyst compositions and polymerization systems include at least one thiourea complex according to Formula (I): MQaX4-a (I) in which M is Ti, Zr, or Hf; a is 1 or 2; each group Q of the thiourea complex is a bidentate thiourea ligand bound to the metal center and having Formula (Ia), Formula (Ib), or Formula (Ic): (Formulas should be inserted here). In Formulas (Ia), (Ib), and (Ic), each group R1, R2, and R3 is independently chosen from alkyl groups or aryl groups; each group Z1 or Z2 is independently chosen from alkylene groups. If a=2, groups R1 of the two groups Q are optionally linked, or groups R3 of the two groups Q are optionally linked. Each X is covalently bonded or coordinated to the metal center and is independently chosen from alkyl groups or halides. The polymerization systems may be configured to copolymerize ethylene and ?-olefins.Type: GrantFiled: September 13, 2017Date of Patent: April 6, 2021Assignee: Dow Global Technologies LLCInventors: Arkady L.

Patent number: 10968300Abstract: A method of increasing a polymerization reaction rate of a base monomer composition that has slow free-radical polymerization kinetics. The method comprises combining an effective amount of a nanogel to the base monomer composition to form a monomer-nanogel mixture having a polymerization reaction rate that is greater than the polymerization reaction rate of the base monomer composition when subjected to an identical free-radical polymerization reaction conducted under identical conditions. The base monomer composition comprises one or more slow-kinetic monomers with slow free radical polymerization kinetics in which <25% of the double bonds are converted within the first 10 mintes of said reaction. The nanogel is soluble in the base monomer composition. The nanogel is derived from a nanogel-forming monomer mixture that comprises: at least one monovinyl monomer; at least one divinyl monomer; a chain transfer agent; and an initiator.Type: GrantFiled: June 23, 2017Date of Patent: April 6, 2021Assignee: THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATEInventors: Jeffrey W.
