Abstract
Abstract Half-ester reaction products possessing unique adhesive properties are obtained by reacting maleated alpha-olefins with hydrocarbylpolyoxyalkylenealkanols. The half-ester in combination with other thermoplastic materials provide improved hot-melt formulations. Paper stocks contaminated with these hot-melt formulations can be recycled into a high grade paper pulp by conventional alkaline repulping processes. The half-ester products are also useful as a solvent in thermoplastic polymerization processes.
