Abstract
A method of preparing a first polymeric compound which comprises providing a compound of the general formula AR1C═CR2B or a salt thereof where A and B are the same or different and at least on group comprises a relatively polar atom or group and R1 and R2 independently comprise relatively non-polar atoms or groups, in a solvent of a type in which ethane itself is greatly insoluble and spacing the C═C groups in said compound to react with one another to form a polymeric structure. The first polymeric compound may be reacted with a second compound, for example polyvinylalcohol, collagen, or the like to produce a colloid or gel which may have applications in the treatment of burns or recovery of oils.
Claims12
A method of preparing a first polymeric compound comprising the following steps:
- (a) providing an aqueous solvent containing a compound having the following formula:
- wherein A is an optionally-substituted aromatic or heteroaromatic group;
- B is an optionally-substituted aromatic or heteroaromatic group;
- A and B are the same or different and at least one comprises a polar atom or group, R1 and R2 independently comprise a non-polar atom or group;
- and
- (b) causing the groups C═C in said compound I to react with one another to form said polymeric compound.
The method of 1, wherein said compound I is in said solvent at a concentration at which molecules of said compound I aggregate.
