US 12,637,543 B2 · Thermoplastic-thermoset hybrid resins, methods, and uses thereof

Abstract

A hybrid thermoplastic-thermosettable resin composition may include a polymeric backbone formed from a thermoplastic unit, and at least one crosslinkable group bonded to the thermoplastic. A method of forming a hybrid thermoplastic-thermosettable resin composition may include reacting a thermoplastic to introduce a cross-linkable group to form the thermoplastic-thermosettable resin composition. A method of forming a hybrid thermoplastic-thermoset resin may include providing a hybrid thermoplastic-thermosettable resin composition comprising a polymeric backbone formed from a thermoplastic unit, and at least one crosslinkable group bonded to the thermoplastic; and curing the hybrid thermoplastic-thermosettable resin composition by an external stimulus to form the hybrid thermoplastic-thermoset resin.

Dependent claims

A hybrid thermoplastic-thermosettable resin composition, comprising:

a polymeric backbone formed from a thermoplastic unit selected from the group consisting of polyimide, polyetherimide, polyaryl ether ketone, polyphenylene sulfide, polysulfone, polyamide-imide and combinations thereof, and
at least one crosslinkable benzoxazine group bonded to the thermoplastic unit,
wherein the at least one crosslinkable benzoxazine group forms at least one endcap on the thermoplastic unit such that a structure of the polymeric backbone and the at least one crosslinkable benzoxazine group corresponds to the one of the following structures:
wherein R is individually selected from a hydrogen atom, a hydrocarbon group, a substituted hydrocarbon group, or a functional group, and PEI is a polyetherimide.
