PROCESS FOR MAKING A POLYZWITTERION OR POLYZWITTERIONIC ACID |
| 摘要 |
A zwitterionic monomer and corresponding cyclopolymerized polyzwitterion (±) (PZ) (i.e. poly(Z-alt-SO2). Phosophonate ester hydroloysis in PZ gave a pH-responsive polyzwitterionic acid (±) (PZA). The PZA under pH-induced transformation was converted into polyzwitterion/anion (±−) (PZAN) and polyzwitterion/dianion (±=) (PZDAN). |

1. A process for making a polyzwitterion or polyzwitterionic acid having the following formula: where n is an integer of 10 or greater, the process comprising: copolymerizing a monomer of formula (I) with SO2 in the presence of a polymerizing agent, wherein R is a C1 to C6 alkyl group or a C6-C12 aryl group or an H group. |
