专利号:US-2024309142-A1 优先权日:2023-03-17 标题 :Capped block copolymers, their synthesis, manufacture, and methods of use 发明人:MAN VICTOR FUK-PONG; LI XIAOJIN HARRY; CHEN YIQING; PU GANG; HUNT JR CLINTON 权利人:ECOLAB USA INC 摘要:This disclosure relates to capped block copolymers, preferably reverse block copolymers capped with a hydrophobic group. Preferred hydrophobic groups include benzyl groups and silyl groups. In a preferred embodiment, the reverse block copolymer has at least two arms, wherein each arm is capped with a hydrophobic group. The disclosure also provides for the synthesis of the capped block copolymers as well as methods of using the capped block copolymers for defoaming and antifoaming applications.

专利号:WO-0018778-A9 优先权日:1998-09-29 标题:Synthesis of codon randomized nucleic acids 发明人:LOHSE PETER; KUIMELIS ROBERT G 权利人:PHYLOS INC 摘要:A method for generating a selected set of codons is disclosed; the method includes the steps of: (a) providing a first set of mononucleosides, mononucleotides, dinucleotides, or mixture thereof, where a subset A of the first set is protected with a protecting group A', and a subset B of the first set is protected with a protecting group B', where A' and B' are orthogonal protecting groups; (b) selectively removing the protecting group A' from subset A; (c) coupling the products of step (b) with a second set of mononucleosides, mononucleotides, dinucleotides, or a mixture thereof, where the second set is protected with protecting group A'; (d) optionally removing protecting group A' from the products of step (c); (e) optionally coupling the products of step (d) with a third set of mononucleosides, where the third set is protected with protecting group A'; (f) selectively removing the protecting group B' from subset B; (g) coupling the products of step (f) with a fourth set of mononucleosides, mononucleotides, dinucleotides, or a mixture thereof, where the fourth set is protected with protecting group A' or protecting group B'; (h) optionally selectively removing protecting group B' from the products of step (g); and (i) optionally coupling the products of step (h) with a fifth set of mononucleosides, to yield a selected set of codons.
专利号:US-11634539-B2 优先权日:2018-09-24 标题:Polycarbonate block copolymers and methods thereof 发明人:ALLEN SCOTT D; DEBNATH DIBYENDU 权利人:SAUDI ARAMCO TECH CO 摘要:The present disclosure relates to block copolymers comprising, and methods of making thereof, a polycarbonate chain linked to a hydrophilic polymer. Such block copolymers may have the formula B-A-B, where A is a polycarbonate or polyethercarbonate chain and B is a polyether. Provided methods are useful in reducing the amount of waste generated from the synthesis of polycarbonates and provide improved thermal stability and high primary hydroxyl content. Provided block copolymers also have utility as additives in enhanced oil recovery methods, and foam polymer applications.
