Claim:
1. A polyhexahydrotriazine (PHT), comprising: a plurality of trivalent hexahydrotriazine groups having the structure; a plurality of divalent bridging groups having the structure;  and a plurality of divalent thermoplastic polymer groups having the structure *-Q-* each having a molecular weight of at least 1000 g/mole, wherein each starred bond of each hexahydrotriazine group is covalently linked to a starred bond of a divalent bridging group or a starred bond of a divalent polymer group, each starred bond of a given bridging group is linked to a respective starred bond of a hexahydrotriazine group, and each starred bond of a divalent polymer group is linked to a respective starred bond of a hexahydrotriazine group, wherein each Q is independently a vinyl polymer chain, a polyether chain, a polyester chain, a polyimide chain, a polyamide chain, a polyurea chain, a polyurethane chain, a polyaryl ether sulfone chain, a polybenzoxazole chain, a polybenzimidazole chain, an epoxy resin, a polysiloxane chain, a polybutadiene chain, a butadiene copolymer, or a combination thereof, and wherein L′ is a divalent linking group selected from the group consisting of —O—, —S—, —N(R′)—, —N(H)—, —R″—, and combinations thereof, wherein R′ and R″ independently comprise at least 1 carbon, wherein a ratio of number of L′ groups to number of Q groups is at least about 30.
