Summary: | Polymeric particles have been prepared by emulsion polymerization of styrene in presence of poly(ethylene glycol) methacrylate (PEGMA). The influence of the functional monomer concentration on the particle size and particle size distribution was studied. Obtained particles show dramatic change of size with temperature. This thermal sensitivity can be influenced by the amount of the PEGMA grafted onto the particle surface as well as by the presence of crosslinking agents in the reaction mixture. It is assumed that particles have a core-shell structure and the brush-like PEGMA-rich shell layer induces the collapse at elevated temperatures.[PUBLICATION ABSTRACT] |
