    摘要: A Process for the preparation of a functionalized terpolymer having general formula (I):




    and including the following steps:



    i) reacting at least one first epoxy compound having general formula (II):












    with at least a second epoxy compound having general formula (III):












    ii) reacting the terpolymer obtained in step i) with at least one sulphur-containing compound having general formula (IV):












    provided that in the general formula (IV) at least one of between R5, R6 and R7 differs from hydrogen and at least one of between R5, R6 and R7, contains one of the following functional groups: —COOH, —COO−M+, —SO3H, —SO3−M+, —SO2H, —SO2−M+, —OPO3H2, —OPO32−M+2, —PO3H2, —PO32−M+2, —OH,






    The above process allows for terpolymers to be obtained which are soluble in polar solvents such as, for example, water, methanol, ethanol, butanol, acetone or dimethyl sulfoxide. The terpolymers can be advantageously used, for example, as additives for cements.

    摘要: The present invention relates to a method for making a polymer wherein during ring opening polymerisation is incorporated into the polymer chain at least one cyclic (alkyl) carbonate monomer having the formula (1) wherein Y is optional and represents the residue of a sulfhydryl reacted group, X represents a functional group reactive with a sulfhydryl group, L=—[CH2]n with n=0-10, or L=—[CH2]p-S—S—[CH2]q with p and q are 0-5 or L=-[PEG]- with PEG is a group that comprises a —[CH2CH2O]m-group with m=1-200, and R2 is hydrogen, methyl or ethyl. Optionally a cyclic (alkyl) acryloyl carbonate, or other additional monomer A may be used as comonomer. The polymer may be formed into a polymer article, such as a polymer film, such as a coating and modified and/or cross linked, to a polymer or polymer article obtainable, and to a biodevice, their use, and to the cyclic (alkyl)carbonates.
