  • Centrally functionalizable living cationic polymer or copolymer and methods of synthesizing the same
    Patent number: 10774185
    Abstract: In various embodiments, the present invention is directed to a centrally-functionalizable living cationic polymer or copolymer having a centrally-substituted tetraene group having the formula wherein each R is selected from the group consisting of a polymer or a copolymer, such as a polyisobutylene polymer or a poly(isobutylene-b-styrene) copolymer.
    Type: Grant
    Filed: January 25, 2019
    Date of Patent: September 15, 2020
    Assignee: The University of Akron

  • Quantitative preparation of allyl telechelic polyisobutylene under reflux conditions
    Patent number: 10329361
    Abstract: In one or more embodiments, the present invention provides a method for forming allyl telechelic polyisobutylene polymers having well defined molecular weights and molecular weight distributions using living cationic polymerization under ideal temperature control using a mixture of polar and nonpolar refluxing solvents. The methods according to various embodiments of the present invention provide temperature control that approaches the ideal, i.e., the heat of polymerization is instantaneously absorbed by the medium and the temperature of the system remains unchanged. The heat generated during the exothermic polymerization of isobutylene is released as an increase in the rate of reflux, rather than the temperature, since the temperature is set by the boiling point of the system and does not change.
