Description
Technical field
The present invention relates to a kind of ATRP reaction macromole evocating agent, particularly a kind of acrylate containing fluorine ATRP macromole evocating agent and preparation method and application.
Background technology
Nineteen ninety-five, reported first such as doctor Wang Jinshan of U.S. Carnegie Mellon University, K.Matyjaszewski transition metal-catalyzed controllable free-radical polymerisation, be referred to as atom transfer radical polymerization (Atom Transfer Radical Polymerization, ATRP).
This method is that activity/controllable free-radical polymerisation has been opened up a brand-new approach.It is an initiator with simple Organohalogen compounds, and transition metal complex is the halogen atom carrier, by redox reaction, sets up running balance between spike and dormancy kind, thereby realizes the control to polyreaction.
It is extensive that the ATRP method has monomer selectivity, the narrow advantages such as (Mw/Mn=1.1～1.5) of synthetic molecular weight distribution.Initiator one end is a halogen atom, the other end can be functional groups such as halogen atom or carboxyl, therefore the existence of functional group can not influence carrying out smoothly of controllable reaction, utilizes the ATRP method can prepare the multipolymer (as block, random, grafting, alternately, gradient, star, comb shape, high branching, crosslinked) and the homopolymer (novel end-functionalization, distant pawl, high branching etc.) of the various topological frameworks that relative molecular weight and end group determine easily.
The ATRP method is one of important means of preparation segmented copolymer.Segmented copolymer has microcosmic and divides phase behavior, and this makes it can have unique macroscopical amphiphilic nature, thereby has broad application prospects in fields such as tensio-active agent, caking agent, coating and polymer blending increase-volumes.Fluorinated block copolymer also has characteristics such as low surface energy, high unreactiveness, thereby enjoy attention in scientific research field and practical application except having macroscopical amphiphilic nature.
