Patent number: 11578159Abstract: The invention relates to the use of low levels of glycols and short chain diols to control air void formation in any polymerization reaction having carbonyl-containing monomers, and preferably carboxylic acid ester 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 glycols and short chain diols are used in the polymization mixture at levels of 0.5 to 10 weight percent, based on the carboxylic acid ester-containing monomer. It is believed the glycols and short chain diols 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 methyl methacrylate polymers and copolymers, either neat, or as a polymer composite system.Type: GrantFiled: December 13, 2017Date of Patent: February 14, 2023Assignee: ARKEMA FRANCEInventors: Alaaeddin Alsbaiee, Evan Crocker, Dana Lee Swan

Patent number: 11491460Abstract: A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.Type: GrantFiled: October 28, 2020Date of Patent: November 8, 2022Assignee: CORNELL UNIVERSITYInventors: William R. Dichtel, Alaaeddin Alsbaiee, Brian J. Smith, Juan Hinestroza, Diego Alzate-Sanchez, Leilei Xiao, Yuhan Ling, Damian Helbling

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

Publication number: 20200071431Abstract: The invention relates to the use of low levels of aliphatic short-chain saturated esters to control air void formation in any exothermic polymerization reaction in which the exotherm exceeds the boiling point of the monomer. One such polymerization is the bulk polymerization of one or more monomers having carboxylic acid ester monomers, at a level of at least 10% of total monomer. The aliphatic short-chain saturated esters are used in the polymerization mixture at levels of 0.5 to 10 weight percent, based on the carboxyl-containing monomer. The invention is especially useful in polymerization of methylmethacrylate polymers and copolymers, either neat, or as a polymer composite system.Type: ApplicationFiled: December 13, 2017Publication date: March 5, 2020Inventors: Alaaeddin Alsbaiee, Evan CROCKER, Dana Lee SWAN
