Abstract
The present invention provides polymers resulting from modification of polymeric moieties containing an anhydride with modifying reactant moieties. The invention further provides a wide variety of compositions comprising the and modified polymeric moieties containing an anhydride. The letters b, d, e, and z are described herein.
Claims13
A polymer resulting from modification of a polymeric moiety containing an anhydride with a modifying reactant moiety, wherein the polymeric moiety containing an anhydride has the structure:
- wherein R1, R2, R3, and R4 are independently selected from the group consisting of hydrogen, alkyl, alkoxy, cycloalkyl, aryl, ester, carboxylic acid, halo, and silyl groups;
- Y is derived from the group consisting of vinyl amides, acrylates, styrenes, maleimides, maleates, fumarates, cinnamyls, vinyl imidazoles, vinyl pyridines, vinyl acetates, acrylamides, vinyl sulfones, vinyl carbonates, vinyl silanes, vinyl acrylamides, allyl derivatives, vinyl ethers, and mixtures thereof;
- and n is an integer ranging from about 10 to about 100,000;
- the modifying reactant moiety is selected from the group consisting of Q-R10—NH2, Z—NH2, and E-OH, and mixtures thereof;
- wherein Q is a siloxane and R10 is selected from the group consisting of alkyl, cycloalkyl, and aryl groups;
- Z is selected from the group consisting of hydrogen, alkyl, haloalkyl, aryl, silyl, and tertiary amine groups having the structure:
- quaternary amine groups having the structure:
- and polyether groups having the structure:
- wherein R5, R6, R7, and R8 are independently selected from the group consisting of alkyl, cycloalkyl, and aryl groups;
- A− is an anion;
- q and p are integers independently ranging from about 1 to about 10,000;
- E is a siloxane or is selected from the group consisting of hydrogen, alkyl, haloalkyl, aryl, silyl, amino groups, and mixtures thereof;
- to provide a modified polymer having the structure:
- wherein R1, R2, R3, and R4 are as described above;
- Q, Z, and E are derived from the modifying reactant moieties as described above;
- M is hydrogen or a monovalent or divalent metal ion;
- a, b, c, d, and e are integers independently ranging from 0 to about 10,000;
- with the proviso that no more than two of a, b, c, d and e can be zero at the same time;
- wherein the polymer is alternating, blocked, or random.
