1. A blocky cationic organopolysiloxane having the structure: wherein: D is [SiR1R2O2/2], x is an integer independently selected from about 40 to about 1000, R1 and R2 are independently selected from the group consisting of H, OH, C1-C32 alkyl, C1-C32 substituted alkyl, C5-C32 aryl, C5-C32 substituted aryl, C6-C32 alkylaryl, C6-32 substituted alkylaryl, C1-C32 alkoxy, C1-C32 substituted alkoxy, wherein:
each X comprises a divalent radical selected from the group consisting of C1-C32 alkylene, C5-C32 arylene, C5-C32 substituted arylene, C6-C32 arylalkylene, C6-C32 substituted arylalkylene, C1-C32 alkyleneamino, and C1-C32 substituted alkyleneamino;each R4 is independently selected from the group consisting of H, C1-C32 alkyl, C1-C32 substituted alkyl, C5-C32 aryl, C5-C32 substituted aryl, C6-C32 alkylaryl, and C6-C32 substituted alkylaryl;N is a nitrogen atom;each R5 is, independently, selected from the group consisting of H, C1-C32 alkyl, C1-C32 substituted alkyl, C5-C32 aryl, C5-C32 substituted aryl, C6-C32 alkylaryl, C6-C32 substituted alkylaryl optionally interrupted with a hetero atom selected from the group consisting of P, N, and O, C1-C32 alkoxy, C1-C32 substituted alkoxy, C1-C32 alkylamino, and C1-C32 substituted alkylamino;each E comprises same or different divalent radicals selected from the group consisting of C1-C32 alkylene, C5-C32 arylene, C5-C32 substituted arylene, C6-C32 arylalkylene, C6-C32 substituted arylalkylene, C1-C32 alkoxy, C1-C32 substituted alkoxy, C1-C32 alkyleneamino, and C1-C32 substituted alkyleneamino;each m is an integer independently selected from 2 to 100,each n is an integer independently selected from 1 or 2,f is an integer from 2 to about 50,and A−t is a suitable charge balancing anion or anions such that the total charge of all occurrences of the charge-balancing anion or anions, A−t and kA−t, is equal to and opposite from the net charge on the blocky cationic organopolysiloxane. |
