    摘要: Non-ionic water-soluble cellulose ethers modified with 3-azido-2-hydroxypropyl groups bound via an ether link are provided having a molar degree of substitution MSAHP in the range from 0.001 to 0.50. Exemplary cellulose ethers are alkyl celluloses, including methyl, hydroxyalkyl (e.g. hydroxyetbyl or hydroxypropyl) or alkylhydroxyalkyl cellulose (e.g. methylhydroxyethyl). Reaction products with alkyne compounds are also provided, resulting in a terminal alkyne group. The reaction of azide with the alkyne proceeds as a 1,3-dipolar cycloaddition reaction, advantageously with Cu(I) or ruthenium catalysts. A multiplicity of cellulose ethers can be obtained from the conversion reaction. Variations in the macroscopic properties can be achieved by controlled modification, ranging from increased or reduced viscosity. The reaction, taking place within a few seconds, requires only minimal catalyst. Gel formation is reversible by adjustment of the pH such that a monophasic system (high-viscous fluid) arises again from a biphasic system (gel+low-viscous water phase).

    摘要: The present invention provides novel hybrid polymers having unique physical properties. The hybrid polymers comprise a cellulose ether moiety, a linking group moiety, a spacer group moiety, and a lactam moiety. The present invention also provides compositions comprising the hybrid polymers and methods for preparing and using the hybrid polymers.
    In a first embodiment, the hybrid polymers have the structure:

    A-(L1-S—(B)k)q

    wherein A is derived from a cellulose ether moiety comprising a —OH group; L1 is a linking group moiety selected from the group consisting of urethanes, amides, esters, carbonates, and phosphate esters, or is derived from a moiety selected from the group consisting of anhydrides, cyclic ethers, and aziridines; S is a spacer group moiety, selected from the group consisting of straight- or branched-chain functionalized and unfunctionalized alkyl, cycloalkyl, alkenyl, and aryl groups, wherein any of the above groups may be with or without heteroatoms, or is a direct bond; and B is a lactam moiety; wherein k≥1 and q≥1.

    In a second embodiment, the hybrid polymers have the structure:

    A-(L2-S—B)y

    wherein A is derived from a cellulose ether moiety comprising a —OH group; L2 is an ether linking group moiety; S is a spacer group moiety, selected from the group consisting of straight- or branched-chain functionalized and unfunctionalized alkyl, cycloalkyl, alkenyl, and aryl groups, wherein any of the above groups may be with or without heteroatoms, or is a direct bond; and B is a lactam moiety; wherein y≥1; with the proviso that when the cellulose ether moiety is hydroxyethyl cellulose, -(L2-S—B)y is not derived from 1-(hydroxymethyl)-2-pyrrolidinone.
