Flame-retardant copolymers of dialkyl (meth) acryloyloxyalkyl phosphate or dialkyl (meth) acryloyloxyalkyl phosphonate monomers and polymer foaming materials made from them.

Title:

Flame-retardant copolymers of dialkyl (meth) acryloyloxyalkyl phosphate or dialkyl (meth) acryloyloxyalkyl phosphonate monomers and polymer foaming materials made from them.

Document Type and Number:

Japanese Patent JP6291059

Kind Code:

B2

Abstract:

Polymer foam bodies are made from phosphorus-containing thermoplastic random copolymers of a dialkyl (meth)acryloyloxyalkyl phosph(on)ate. Foam bodies made from these copolymers exhibit increased limiting oxygen indices and surprisingly have good properties. In certain embodiments, the phosphorus-containing thermoplastic copolymer is blended with one or more other polymers and formed into nanofoams.
