  • Patent number: 10844166
    Abstract: The present invention relates to a thermoplastic copolymer, block copolymer, and statistical copolymer comprising plural acrylated polyol monomeric units having different degrees of acrylation of hydroxyl groups. The acrylated polyol monomeric units have an average degree of acrylation greater than 1 and less than the number of the hydroxyl groups of the polyol. The present invention also relates to a method of making the thermoplastic copolymer, block copolymer, and statistical copolymer, and using them in various applications, such as asphalt rubber modifiers, adhesives, or an additive in a fracking fluid for oil fracking.
    Type: Grant
    Filed: December 7, 2018
    Date of Patent: November 24, 2020
    Assignee: IOWA STATE UNIVERSITY RESEARCH FOUNDATION, INC.
