Abstract:
A silicone polymer which conforms to the following structure:(R1)aR3âˆ’aSiâ€”(â€”Oâ€”SiR2)mâ€”(â€”Oâ€”SiRA)nâ€”(â€”Oâ€”SiRB)pâ€”(â€”Oâ€”SiRD)qâ€”[OSiR2â€”Jâ€”(G)gâ€”(J)jâ€”(E)kâ€”Jâ€”SiR2]râ€”Oâ€”Si(R1)bR3âˆ’b wherein:each R is the same or different and is selected from the group consisting of alkyl, aryl, and mixtures thereof; each A is the same or different and is selected from the group consisting of hydrogen, â€”OH, â€”OR, â€”OCOCH3, â€”CH2CH2Si(OR)3, â€”CH2CH2Si(OR)2R, â€”CH2CH2Si(OR)R2, and mixtures thereof; each optional B is an â€”Xâ€”E group with each X being a hydrocarbon or oxygenated hydrocaxbon linking group, and each E being a cationic nitrogen functional group; each optional D is a poly(ethyleneoxy/propyleneoxy) group having the structure: â€”Zâ€”O(C2H4O)c(C3H6O)dR3 wherein each Z is a linking group, selected from the group consisting of hydrocarbon linking group, oxygenated hydrocarbon linking group, aminohydrocarbon linking group, and mixtures thereof; each R3 is the same or different and is selected from the group consisting of hydrogen, R, E, JE, â€”CH2CH(R)OH, â€”CH2C(R)2OH, â€”CH2CH(OH)CH2OR, â€”CH2CH(OH)CH2(OCH2CH2)eOR, tetrahydropyranyl, â€”CH(R)OR, C(O)H, â€”C(O)R, and mixtures thereof; each c is at least about 2, total c (for all polyalkyleneoxy pendant groups) has a value of from about 4 to about 2500; total d has a value of from 0 to about 1000, c is equal or larger than d; and each e is from 1 to about 20;each optional G is â€”O(C2H4O)v(C3H6O)wâ€”; each J is selected from the group consisting of X, â€”CH2CH(OH)CH2â€”, and mixtures thereof; each v is from 0 to about 200; each w is from 0 to about 50, and v is equal or larger than w; each g and k is from 0 to about 10; j is g+kâˆ’1, providing that no Oâ€”O bonds are formed; each R1 group is selected from the same or different group and is selected from the group consisting of R, A, B, and D; each a and b is an integer from 0 to 3; m is from about 5 to about 1600; n, a, and b, and the R1 groups are selected such that the silicone polymer comprises at least one reactive Si functional group in the form of an Siâ€”A group, selected from the group consisting of Siâ€”H, Siâ€”OH, Siâ€”OR, Siâ€”OCOR, and mixtures thereof; wherein a ratio of n to (m+n) is from 0 to about 1:2; and when p is not 0, a ratio of n to (m+n+p) is from 0 to about 1:2; p, a, and b, and the R1 groups are selected such that the silicone polymer optionally comprises at least one cationic group in the form of an Siâ€”B group; wherein a ratio of p to (m+n+p) is from 0 to about 1:2; q, a, and b, and the R1 groups are selected such that the silicone polymer optionally comprises at least one poly(ethyleneoxy/propyleneoxy) Siâ€”D group; wherein a ratio of q to (m+n+p+q) is from about 1:1000 to about 1:3; and r is from 0 to about 100, with r being 0 when neither a polyalkyleneoxy group nor a cationic group is part of the polymer backbone; and when one or more polyalkyleneoxy groups and/or cationic groups are part of the polymer backbone, a ratio of r to (m+n+p) is from about 1:1000 to about 1:2; wherein the different â€”Oâ€”SiR2â€”, â€”Oâ€”SiRAâ€”, â€”Oâ€”SiRBâ€”, and â€”Oâ€”SiRDâ€” groups can be distributed randomly in the silicone backbone and/or organized as block copolymers of different degrees.
