Abstract
A flame retardant sugar-derived molecule, a process for forming a flame retardant sugar-derived molecule, and an article of manufacture comprising a flame retardant sugar-derived molecule are disclosed. The flame retardant sugar-derived molecule can be synthesized from arabitol, xylitol, arabic acid, or xylonic acid obtained from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety. The process for forming the flame retardant sugar-derived molecule can include reacting arabitol, xylitol, arabic acid, or xylonic acid and a flame retardant phosphorus-based molecule to form the flame retardant sugar-derived molecule.

- wherein X is selected from a group consisting of a methanediyl moiety and a carbonyl moiety;
- wherein FR is a phosphorus-based moiety;
- wherein R1 is a substituent selected from a group consisting of an allyl substituent, an epoxide substituent, a propylene carbonate substituent, a phenyl substituent, and a thioether substituent;
- wherein R2 is a substituent selected from a group consisting of an allyl substituent, an epoxide substituent, a propylene carbonate substituent, a phenyl substituent, and a thioether substituent;
- wherein R3 is a substituent selected from a group consisting of an allyl substituent, an epoxide substituent, a propylene carbonate substituent, a phenyl substituent, and a thioether substituent;
- wherein R4 is a substituent selected from a group consisting of an allyl substituent, an epoxide substituent, a propylene carbonate substituent, a phenyl substituent, and a thioether substituent;
- wherein R5 is a substituent selected from a group consisting of an allyl substituent, an epoxide substituent, a propylene carbonate substituent, a phenyl substituent, and a thioether substituent;
- wherein the selection of R1 limits the selection of R2, R3, R4, and R5;
- wherein the selection of R2limits the selection of R1, R3, R4, and R5;
- wherein the selection of R3 limits the selection of R1, R2, R4, and R5;
- wherein the selection of R4 limits the selection of R1, R2, R3, and R5;
- and
- wherein the selection of R5 limits the selection of R1, R2, R3, and R4.
A process of forming a flame retardant polymer, comprising:
- obtaining a phosphorus-based flame retardant molecule;
- obtaining a sugar-derived molecule;
- chemically reacting the sugar-derived molecule with the phosphorus-based flame retardant molecule to form a flame retardant sugar-derived molecule;
- and
- processing the functionalized flame retardant sugar-derived molecule into a polymer.
An article of manufacture, comprising a material containing a flame retardant sugar-derived molecule.
