| titleOfInvention | A kind of preparation method and application of photochromic chain-transferring agent |
| abstract | The invention discloses a kind of preparation method and application of photochromic chain-transferring agent.By spiro-pyrans class compound, trithiocarbonic acid esters chain-transferring agent through esterification, a kind of novel photochromic chain-transferring agent is synthesized, compound structure is as shown in formula I.Again using compound shown in formula I as chain-transferring agent, to the reversible addition-fragmentation chain transfer free radical polymerization of styrene（RAFT）Behavior is investigated, and the obtained polymer with photochromic properties is coated on silicon chip by spin coater, obtains the thin polymer film with photochromic properties.Photochromic group is incorporated into RAFT agent structure by the present invention, prepare the chain-transferring agent with photochromic properties, the active free radical polymerization of the monomers such as styrene can be successfully carried out, so as to obtain that there is the functional polymer that photochromic function, molecular weight are controllable, molecular weight distribution is narrower. |
