Abstract
Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. High-performance characteristics are incorporated into the polymer by using aromatic polycarbonate, aromatic polyester, polyarylsulfide, and polyarylimidazolidine oligomers. The compositions are useful as hot-melt adhesives, coatings and especially finish surface coatings on composite materials such as polypropylene and polyethylene terephthalate, moldings and in injection reaction molding applications and composite and laminate fabrication.
