Abstract
A polymeric polysulfide is disclosed. The polymeric polysulfide is formed by reacting a fatty acid composition comprising at least one unsaturated fatty acid or derivative thereof with sulfur, at a weight ratio between 9:1 and 1:9, under inverse vulcanisation conditions to produce a polymeric polysulfide wherein at least 50% of the fatty acids or derivatives thereof in the fatty acid composition are unsaturated.
Claims19
A polymeric polysulfide formed by reacting a fatty acid composition comprising at least one unsaturated fatty acid or derivative thereof with sulfur, at a weight ratio between 2:1 and 1:2, under inverse vulcanisation conditions to produce a polymeric polysulfide wherein at least 50% of the fatty acids or derivatives thereof in the fatty acid composition are unsaturated.
A method for producing a polymeric polysulfide, the method comprising:
- providing a fatty acid composition comprising at least one unsaturated fatty acid or derivative thereof and wherein at least 50% of the fatty acids or derivatives thereof in the fatty, acid composition are unsaturated;
- reacting the fatty acid composition with molten sulfur at a weight ratio between 2:1 and 1:2 under conditions to produce the polymeric polysulfide.
A metal removal composition comprising a polymeric polysulfide, wherein the polymeric polysulfide is formed by reacting a fatty acid composition comprising at least one unsaturated fatty acid or derivative thereof with sulfur, at a weight ratio between 2:1 and 1:2, under inverse vulcanisation conditions to produce a polymeric polysulfide wherein at least 50% of the fatty acids or derivatives thereof in the fatty acid composition are unsaturated, and wherein the metal removal composition is suitable for removing one or more metals or metal ions from a metal or metal ion containing composition or surface.
