Phenoxy resins containing pendent ethynyl groups and cured resins therefrom
Technical Report
·
OSTI ID:6466445
Phenoxy resins containing pendent ethynyl groups, the process for preparing the same, and the cured resin products obtained therefrom, are discussed. Upon the application of heat, the ethynyl groups react to provide branching and crosslinking. The cure temperature can be lowered by using a catalyst, but this step is not required. The cured phenoxy resins containing pendent ethynyl groups have improved solvent resistance and higher use temperature than linear uncrosslinked phenoxy resins. These improved thermoplastics are applicable for use as coatings, films, adhesives, composited matrices, and molding compounds.
