Abstract
A composition, comprising a poly(methylene lactide) polymer covalently linked to a hexahydrotriazine unit or a hemiaminal unit, and methods of making such a composition, are described herein. In one embodiment, the poly(methylene lactide) polymer comprises a plurality of poly(methylene lactide) chains, and at least a portion of the poly(methylene lactide) chains are cross-linked by one or more of the hexahydrotriazine units, the hemiaminal units, or a combination thereof.
Claims17
A composition, comprising:
- a poly(methylene lactide) polymer covalently linked to a hexahydrotriazine unit having the structure
- a hemiaminal unit having the structure
- or combinations thereof, wherein at least one starred bond of the hexahydrotriazine unit, the hemiaminal unit, or combinations thereof represents a connection to a bridging group.
A composition, comprising:
- a poly(methylene lactide) polymer covalently linked to a poly(hexahydrotriazine), a poly(hemiaminal), or combinations thereof, by an aromatic bridging group, wherein:
- the poly(hexahydrotriazine) is a material having a plurality of hexahydrotriazine units having the structure
- the poly(hemiaminal) polymer is a material having a plurality of hemiaminal units having the structure
- and
- at least one starred bond of the hexahydrotriazine unit or the hemiaminal unit represents a connection to the aromatic bridging group.
A composition, comprising:
- a poly(methylene lactide) polymer covalently linked to a hexahydrotriazine unit, wherein the hexahydrotriazine unit has the structure
- and wherein at least one starred bond represents a connection to an aromatic bridging group.
