A new bifunctional coupling agent: Synthesis and model reactions

Abstract

The preparation of a new bifunctional coupling agent with one oxazoline group and one oxazinone group has been described. Model reactions with dodecanoic acid, benzoic acid, n-dodecyl alcohol and n-dodecylamine in melt evidenced that both carboxylic acids react selectively with the oxazoline group whereas the oxazinone group is exclusively attacked by the amino and the hydroxy compound, respectively. In blends of amino group terminated polyethers with a carboxy group containing polyethylene the new coupling agent has proven very effective.
