Abstract
A flame retardant acrylic/polylactic acid (PLA) copolymer is synthesized which contains a FR-PMMA block that includes either a poly(MMAP) block or a poly(MMA-co-MMAP) block, wherein MMA is methyl methacrylate and MMAP is a MMA-like monomer that is functionalized with a phosphorus-containing moiety. In some embodiments, the flame retardant acrylic/PLA copolymer is a diblock copolymer containing a PLA block and a FR-PMMA block. In other embodiments, the flame retardant acrylic/PLA copolymer is a triblock-graft copolymer containing a PLA block, a PMMA block and a FR-PMMA block.

A flame retardant acrylic/polylactic acid (PLA) copolymer, comprising:
- a diblock copolymer containing a PLA block and either a poly(MMAP) block or a poly(MMA-co-MMAP) block, wherein MMA is methyl methacrylate and MMAP is a MMA-like monomer that is functionalized with a phosphorus-containing moiety.
A flame retardant acrylic/polylactic acid (PLA) copolymer, comprising:
- a triblock-graft copolymer containing PLA grafted outer blocks, linear PMMA outer blocks, and either a linear poly(MMAP) inner block or a linear poly(MMA-co-MMAP) inner block, wherein MMA is methyl methacrylate and MMAP is a MMA-like monomer that is functionalized with a phosphorus-containing moiety.
A flame retardant acrylic/polylactic acid (PLA) copolymer, comprising:
- a triblock-graft copolymer containing PLA grafted outer blocks, a linear PMMA block, and either poly(MMAP) grafted inner blocks or poly(MMA-co-MMAP) grafted inner blocks, wherein MMA is methyl methacrylate and MMAP is a MMA-like monomer that is functionalized with a phosphorus-containing moiety.
