The invention provides a method of producing a degradable polymeric material by preparing an intercalated double hydroxide of the general formula (I) in which MII represents a single metal ion or more than one metal ion selected from V, Cr, Mn, Fe, Co, Ni, Cu, Zn and Sn and MIII represents a single metal ion or more than one metal ion selected from Al, V, Cr, Mn, Fe, Co, Ni, Nb, Mo, In, W and Ce. A is selected from C8 to C24 straight or branched chain carboxylic acids and mixtures thereof and, optionally, at least one further component selected from an anionic surfactant, a straight or branched chain C8 to C24 amine, a straight or branched chain C8 to C24 alcohol and a straight or branched chain C8 to C24 aldehyde. The intercalated double hydroxide is combined with at least one polymeric substrate and, optionally, at least one additional component selected from anti-oxidants and degradation susceptible polymers to produce a mixture which is compounded to produce the degradable polymeric material. |
