Abstract:
1. A process for the anionic polymerization of anionically polymerizable compounds comprising the steps of: initiating polymerization of one or more compounds capable of anionic polymerization in a hydrocarbon or mixed hydrocarbon-polar solvent medium with one or more compounds having the formula: to produce an intermediate living polymer, wherein: M is an alkali metal selected from the group consisting of lithium, sodium and potassium; Z is a branched or straight chain hydrocarbon connecting group which contains 3-25 carbon atoms, optionally substituted with aryl or substituted aryl; Q is a saturated or unsaturated hydrocarbyl group derived by the incorporation of one or more unsaturated organic compounds into the M-Z linkage; n is from 0 to 5; R R or each R wherein y is from 1 to 4 and each R 11 is independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, cycloalkyl, substituted cycloalkyl, alkoxy, substituted alkoxy, heteroaryl, substituted heteroaryl, heterocycloalkyl, and substituted heterocycloalkyl; reacting the intermediate living polymer with a terminating, functionalizing, or coupling agent; optionally removing at least one protecting group to liberate at least one functional group; and optionally reacting said at least one liberated functional group with one or more comonomers to form a polymer segment.
