Document Type and Number:
Japanese Patent JP2005528489
Kind Code:
A
Abstract:
A method of preparing a dispersion which includes the step of contacting a first phase, a first material immiscible therewith, a first polymeric material and a second polymeric material wherein: (a) (i) said first polymeric material has a repeat unit of the formula (I), wherein A and B are the same or different, are selected from optionally-substituted aromatic and thereoaromatic groups and at least one comprises a relatively polar atom or group and R1 and R2 independently comprise relatively non-polar atoms or groups; (ii) said first polymeric material is prepared or preparable by providing a compound of general formula (I), wherein A, B, R1 and R2 are as described above, in an aqueous solvent and causing the groups C-C in said compound to react with one another to form said first polymeric material; (b) said second polymeric material includes a functional group which is able to react with said first polymeric material so that covalent bonds are formed between said first and second polymeric materials; (c) the ratio of the weight of said first polymeric material to the weight of said first phase is equal to or less than 0.0025; and (d) the ratio of the weight of said second polymeric material to the weight of said first phase is equal to or less than 0.035.
