ABSTRACT:
A poly(arylene ether) polymer includes polymer repeat units of the following structure:in-line-formulae description="In-line Formulae" end="lead"?—(O—Ar1—O—Ar2)m—(O—Ar3—O—Ar4)n—in-line-formulae description="In-line Formulae" end="tail"?where Ar1, Ar2, Ar3, and Ar4are identical or different aryl radicals, m is 0.05 to 0.95, n is 1-m, and at least one of the aryl radicals is grafted to at least one hydroxyalkyl group, such as 2-undecanol. The polymer is especially useful in electrically conductive adhesives.
