  • Patent number: 11440995
    Abstract: A method for preparing aliphatic polythioether is provided. In the method, aliphatic polythioether is obtained by polymerization reaction using a sulfur-carbon compound and an oxygen-containing monomer as raw materials and using Lewis base as a catalyst, and the polymerization reaction is performed under a self-generated pressure at 80˜180° C. Based on the defects of the traditional preparation process of aliphatic polythioether, a bran-new synthetic routine is provided, in which a new process for preparing polythioether in one-pot reaction is achieved through oxygen-sulfur exchange reaction between the sulfur-carbon compound and the oxygen-containing monomer.

  • Patent number: 11427682
    Abstract: The invention provides a new class of synthetic sequence-defined polymer (SDP) and a method of synthesizing the same. The synthetic sequence-defined polymers have dithiocarbamate incorporated to the backbone. The method introduces a functional group dithiocarbamate in the backbone by using a new support-free, protection-deprotection free three-component reaction strategy. Dithiocarbamate-SDP is prepared from a unique bifunctional monomer, CS2 and chloroacetyl chloride. Chloracetyl chloride is used as a co-monomer. Different functional groups may be introduced in the dithiocarbamate-SDP via custom synthesis of monomers with the desired functional group, using the method disclosed. The SDPs may undergo modular post-synthetic modification through multiple paths. SDP is produced in multi-gram scale at low cost and in an eco-friendly manner through the method. No hazardous waste is produced in the process as HCl gas released from the reaction may be neutralized by bicarbonate in the medium.
