1. An article comprising a synthetic blend copolymer prepared by polymerization of a compound having a formula I
wherein,
R1 is a long chain fluorinated alkyl that is a straight chain or a branched chain alkyl group having 5 to 12 carbon atoms in a longest continuous chain of carbon atoms as counted from a point of attachment of the longest continuous chain of carbon atoms to a silicon atom at any apex of a silicon-oxide core, where at least one hydrogen atom in the straight chain or the branched chain alkyl group is replaced by a fluorine atom;
R2 is selected from the group consisting of C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C6-C10 aryl, C3-C8 cycloalkyl, 5-7 membered heterocyclic and 5-7 membered heteroaryl, wherein each hydrogen atom in R2 is independently optionally substituted by an R3;
R3 is —OC(O)R4 or —OC(O)OR4;
R4 is methyl, wherein each hydrogen atom in R4 is independently optionally substituted by an R6;
each R6 is independently selected from the group consisting of halo, C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C6-C10 aryl, C3-C8 cycloalkyl, 5-7 membered heterocyclic, 5-7 membered heteroaryl, —NCO, —OR7, —NR7R8, —OC(O)R7, —C(O)OR7, —C(O)R7, —OC(O)OR7, —C(O)NR7R8, —OC(O)NR7R8, —NR7C(O)R8, —NR7C(O)OR8 and —NR7C(O)NR7R8, and when R6 is C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C6-C10 aryl, C3-C8 cycloalkyl, 5-7 membered heterocyclic or 5-7 membered heteroaryl, each hydrogen atom in R6 is independently optionally substituted by an R9;
each R7 and R8 is independently selected from the group consisting of hydrogen, C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C6-C10 aryl, C3-C8 cycloalkyl, 5-7 membered heterocyclic and 5-7 membered heteroaryl, wherein each hydrogen atom in R7 and R8 is independently optionally substituted by one or more R9;
each R9 is independently selected from the group consisting of hydrogen, halo, C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C6-C10 aryl, C3-C8 cycloalkyl, 5-7 membered heterocyclic, 5-7 membered heteroaryl, —NCO, —OR10, —NR10R11, —OC(O)R10, —C(O)OR10, —C(O)R10, OC(O)OR10, —C(O)NR10R11, —OC(O)NR10R11, —NR10C(O)R11, —NR10C(O)OR11 and NR10C(O)NR10R11, and when R9 is C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C6-C10 aryl, C3-C8 cycloalkyl, 5-7 membered heterocyclic, C3-C8 cycloalkyl or 5-7 membered heteroaryl, each hydrogen in R9 is independently optionally substituted by a moiety selected from the group consisting of halo, —NCO, —OR10, —NR10R11, —OC(O)R10, —C(O)OR10, —C(O)R10, OC(O)OR10, C(O)NR10R11, —OC(O)NR10R11, —NR10C(O)R11, —NR10C(O)OR11 and NR10C(O)NR10R11;
each R10 and R11 is independently selected from the group consisting of H, C1-C8 alkyl, C2-C8 alkenyl and C2-C8 alkynyl, and when R10 or R11 are C1-C8 alkyl, C2-C8 alkenyl or C2-C8 alkynyl, each hydrogen atom in R10 and R11 is independently optionally substituted by a fluorine atom;
n is an integer from 1 to 7; and,
each R10 and R11 is independently covalently attached at a silicon atom,
with at least one monomer; wherein the compound of the formula I is prepared by a process comprising:
(a) contacting a compound of the formula R1Si(ORA)3 with a compound of the formula R2Si(ORA)3, in the presence of a base, wherein —ORA is a C1-C8 alkoxy, and the —ORA on R1Si(ORA)3 and R2Si(ORA)3 can be the same or different.
