Abstract

A flame-retardant vanillin-derived molecule, a process for forming a flame-retardant resin, and an article of manufacture comprising a material that contains the flame-retardant vanillin-derived molecule are disclosed. The flame-retardant vanillin-derived molecule can be synthesized from vanillin obtained from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety with phenyl, allyl, epoxide, propylene carbonate, or thioether substituents. The process for forming the flame-retardant resin can include reacting a vanillin derivative and a flame-retardant phosphorus-based molecule to form the flame-retardant vanillin-derived molecule, and binding the flame-retardant vanillin-derived molecule to a resin. The flame-retardant vanillin-derived molecules can also be bound to polymers. The material in the article of manufacture can be flame-retardant, and contain the flame-retardant vanillin-derived molecules. Examples of materials that can be in the article of manufacture can include resins, plastics, adhesives, polymers, etc.

First claim

What is claimed is:

1. A bondable flame-retardant vanillin-derived molecule with a formula of:

wherein M is a flame-retardant substituent; and
wherein FR is a phosphorus-based moiety.

2. The flame-retardant vanillin-derived molecule of claim 1 , wherein the M is selected from a group consisting of substituents with formulas of:

wherein FR is a second phosphorus-based moiety; and
wherein R is a substituent selected from a group consisting of an allyl substituent, an epoxide substituent, a propylene carbonate substituent, and a thioether substituent.

3. The flame-retardant vanillin-derived molecule of claim 1 , wherein the FR is a phosphoryl moiety with a formula of:

4. The flame-retardant vanillin-derived molecule of claim 1 , wherein the FR is a phosphonyl moiety with a formula of:

5. The flame-retardant vanillin-derived molecule of claim 2 , wherein the thioether substituent is selected from a group consisting of a hydroxyl-functionalized thioether substituent, an amino-functionalized thioether substituent, and a carboxylic acid-functionalized thioether substituent.

6. The flame-retardant vanillin-derived molecule of claim 1 , wherein the flame-retardant vanillin-derived molecule is bound to a resin.

7. The flame-retardant vanillin-derived molecule of claim 1 , wherein the flame-retardant vanillin-derived molecule is bound to a polymer.
