Notes:
The polymer particles with an heterogeneous structure are synthesised in emulsion using the method of the continued addition of monomers in two successive stages. The last fraction contains a mixture with an excess of reactive monomer. The core structure is made with a copolymer of n-butylacrylate (BuA) and butylmethacrylate (BuMA), the shell structure with a terpolymer of BuA, BuMA and glycidylmethacrylate (MAG).The classical epoxy group titrations which have been carried out have allowed the appraisal of the particle's superficial reactivity which is weak (about 5 to 10%) and the total concentration of oxirane functions, which is about 90%. This means the initiator redox system and the general polymerisation conditions are favorable for the epoxy function preservation.A gas chromatography essay of sampling was used for the kinetic tracing studies of polymerisation which gives an interesting schematic representation of the particle microstructure. The radial display of glycidylmethacrylate (MAG) in the particle will be examined in detail.
