Title:
STORAGE STABLE AQUEOUS ORGANIC PEROXIDE EMULSIONS
Document Type and Number:
WIPO Patent Application WO2002076936
Kind Code:
A8
Abstract:
The invention relates to an aqueous organic peroxide emulsion comprising an anti-freeze agent, a protective colloid, and a plasticiser wherein the plasticiser is an ester having a ratio of the number of carbon atoms present in the plasticiser molecule (excluding aromatic carbon atoms) to the number of ester groups in the molecule of higher than 8. These emulsions show a reduced droplet growth as compared to emulsions comprising a conventional plasticiser, i.e. the emulsions of the invention are more stable upon storage than the emulsions of the prior art. The invention emulsions are particularly useful in polymerisation processes such as the polymerisation of vinyl chloride monomer.
