Preparation of Miniemulsion and Nanocapsules by Reversible Addition-Fragmentation Chain Transfer and Chemical Shearing Method
Abstract The amphiphilic reversible addition-fragmentation chain transfer(RAFT) agent with multi-carboxylic acid groups was used as the surfactant precursor to prepare the miniemulsion of styrene and paraffin by chemical shearing method. It was found that the sub-micrometer particles could be prepared by chemical shearing, and the compositions and structures of the RAFT agents had significant influence on the formation of miniemulsions. The poly(AAm-b-Stn)RAFT and poly(MAAm-co-Stn)RAFT showed better emulsifying ability. The well-defined nanocapsules of paraffin(core-structure nanocapsule particles) could be obtained using the two RAFT agents by interfacial miniemulsion polymerization, and the polymerization was more stable using the first RAFT.
