Abstract
A process of forming a flame retardant polylactide includes forming a flame retardant lactide monomer. The process also includes forming a lactide feedstock that includes at least the flame retardant lactide monomer. The process further includes polymerizing the lactide feedstock to form a flame retardant polylactide.
Claims15
A process of forming a flame retardant polylactide, the process comprising:
- forming a flame retardant lactide monomer, wherein the flame retardant lactide monomer comprises at least one diphosphate lactide monomer;
- forming a lactide feedstock that includes at least the flame retardant lactide monomer;
- and
- polymerizing the lactide feedstock to form a flame retardant polylactide.

A flame retardant polylactide formed by a process comprising:
- forming a lactide feedstock comprising at least a flame retardant lactide monomer, wherein the flame retardant lactide monomer comprises at least one diphosphate group lactide monomer;
- and
- polymerizing the lactide feedstock to form the flame retardant polylactide.
An article of manufacture formed by a process comprising:
- forming a lactide feedstock comprising a first amount of an L-lactide monomer and a second amount of a flame retardant lactide monomer, wherein the flame retardant lactide monomer comprises at least one diphosphate lactide monomer;
- polymerizing the lactide feedstock to form a flame retardant polylactide;
- forming a blend comprising the flame retardant polylactide and a second polymeric material;
- and
- forming an article of manufacture from the blend, wherein the second amount of the flame retardant lactide monomer in the lactide feedstock is selected such that the article of manufacture has flame retardancy characteristics that satisfy a plastics flammability standard.
