The morphology control of Core-shell-like latex particles is an important area of research in the field of latex emulsion polymer , which is drawing widespread attention recently. Compared with random copolymers and simple blends polymers, Core-shell-like latex particles have many excellent properties and are widely applied in many fields such as coatings, adhesives, plastics, biotechnology and so on. Core-shell-like latex particles with clear profileis were not obtained by superposing simple polymers, but by controlling the polymerization kinetics and thermodynamics. In the precess of separating many latex particles, Domestic and foreign literatures have reported many intermediate phases, such as: RP structure, island-type structure, sandwich-type structure, etc.. However, there are few reports about how to prepare Core-shell-like latex particles with narrow distribution of multi-layer strawberry structure. [ Last edited by IASCC on 2010-6-26 at 13:31 ] |
