| titleOfInvention | Process for producing homo-and co-polymers by raft emulsion polymerization |
| abstract | A novel process to produce homo- and co-polymers by RAFT polymerization in emulsion is here disclosed. The invention mixes to different existing technologies: emulsion polymerization and living free radical polymerization (LFRP) by RAFT. Emulsion provides the necessary radical segregation in order to reduce bimolecular terminations and to increase the polymerization rate. The presence of the RAFT agent assures the living mechanism. RAFT agents are often characterized by very low water solubility and, once put in emulsion, they do not participate the reaction. On the other hand, compounds able to form a water soluble complex with the RAFT agent (e.g., cyclodextrins) can help the transport across the water phase of the RAFT agent to the polymer particles. Accordingly, chains can grow through the entire process in a highly controlled way. This generally leads to the production of low polydispersity polymers with well defined structure and end functionalities. It is worth noting that, since the RAFT reaction does not affect the radical concentration in the particle, the same polymerization rate as in a conventional polymerization process is obtained. Moreover, since polymer chains are still living at the end of the process, they can be restarted thus producing block copolymers. |
