Abstract:
A method for forming a functionalized polymer comprising the steps of providing a living lithium polymer; and terminating the living lithium polymer with an oxazoline compound according to the following formula (I): wherein R1 is selected from the group consisting of: an organic halide according to the following formula (II): wherein each R6 may be the same or different and is selected from the group consisting of a branched or linear C1-C20 alkyl moiety, a C3-C20 cycloalkyl moiety, a C6-C20 aryl moiety, and a C7-C20 alkylaryl moiety, R7 is selected from the group consisting of a branched or linear C1-C20 alkylene moiety, a C4-C20 cycloalkylene moiety, and a C7-C20 alkylarylene moiety, and X is a halogen; a branched or unbranched vinyl moiety according to the following formula (III): wherein R8 is selected from the group consisting of hydrogen, a branched or linear C1-C20 alkyl moiety, a C3-C20 cycloalkyl moiety, a C6-C20 aryl moiety, and a C7-C20 alkylaryl moiety; a moiety according to formula (IV): wherein each R6 may be the same or different and is selected according to the same criteria set forth in formula (II); and hydrogen; and R2-R5 may be the same or different and are selected from the group consisting of: hydrogen; an organic halide, â€”R7â€”X, wherein R7 is as already defined; and a branched or linear C1-C20 alkyl moiety, a C3-C20 cycloalkyl moiety, a C6-C20 aryl moiety, and a C7-C20 alkylaryl moiety, with the proviso that, if R1 is selected from either an organic halide according to formula (II) or a vinyl moiety according to formula (III), R2-R5 are selected from the group consisting of hydrogen, a branched or linear C1-C20 alkyl moiety, a C3-C20 cycloalkyl moiety, a C6-C20 aryl moiety, and a C7-C20 alkylaryl moiety, and, if R1 is selected from either hydrogen or a moiety according to formula (IV), one of R2-R5 is selected from an organic halide â€”R7â€”X, and the other R2-R5 groups are selected from the group consisting of hydrogen, a branched or linear C1-C20 alkyl moiety, a C3-C20 cycloalkyl moiety, a C6-C20 aryl moiety, and a C7-C20 alkylaryl moiety.
