AMPHIPHILIC BRANCHED COPOLYMER, METHODS OF PREPARATION, EMULSIONS, AND USES |
摘要 |
The present invention relates to an amphiphilic branched copolymer obtainable by an addition polymerisation process, the method of production of same and uses thereof as emulsions wherein said polymer comprises: at least two chains which are covalently linked by a bridge other than at their ends; and wherein the at least two chains comprise at least one ethylenically monounsaturated monomer, and wherein the bridge comprises at least one ethylenically polyunsaturated monomer; and wherein the polymer comprises a residue of a chain transfer agent and optionally a residue of an initiator, and wherein at least one of the monounsaturated monomer(s) and polyunsaturated monomer(s) and chain transfer agent(s) is a hydrophilic residue; and at least one of one of the monounsaturated monomer(s) and polyunsaturated monomer(s) and chain transfer agent(s) is a hydrophobic residue, and wherein the mole ratio of polyunsaturated monomer(s) to monounsaturated monomer(s) is in a range of from 1:100 to 1:4, and wherein at least one of the monounsaturated monomer(s) and polyunsaturated monomer(s) and chain transfer agent(s) comprises a moiety that is capable of responding to an external stimuli thereby creating a physical or chemical change in the solubility of the said moiety; and wherein the air-water surface tension of the polymer changes from between 35 mN/m to 60 mN/m upon application of the external stimulus. |
