Abstract: Methods of preparing a polyaniline homopolymer or copolymer comprising at least one carboxylic acid group, and homopolymers or copolymers arising therefrom, the methods comprising: preparing a solution of a polyaniline precursor having at least one aromatic amine group and at least one carboxylic acid group (eg. 2-aminobenzoic acid, 3-aminobenzoic acid or 4-aminobenzoic acid) in a solvent selected from aqueous methanesulfonic acid or aqueous ammonia and optionally one or more additional polyaniline precursors (such as aniline); and oxidatively polymerising the polyaniline precursor or precursors.

Abstract: A fire retardant material comprising preferably at least 60% polypropylene having a flexural modulus of 2.8 GPa or above and a fire retardancy rating of UL-94 V-1 or better. The fire retardant material is preferably halogen and glass-fiber free. It may contain a fire retardant agent (e.g. a polymeric APP-crystal phase II type fire retardant fire retardant) and a filler. Also methods for producing such a fire retardant material.

Abstract: Aniline copolymers and the synthesis thereof for use as antimicrobial (antibacterial, antifungal or antiviral material) material of for the manufacture of antimicrobial objects, suitable for use in the health, food, packaging, water, paint, wood, textile, poultry, glass, paper, rubber, ceramic, seafood, sports, plastic and agricultural industries. The copolymer may be for example (A): where for example R3=H5—CO2H, —CO2Me, or —CO2Et. R is typically H or a C1-C6 alkyl, x is an integer between 1 and 0 and m indicates the degree of polymerisation. Preferred copolymers are copolymers of aniline with 3-aminobenzoic acid, 2-aminobenzoic acid and ethyl 3-aminobenzoate.
