Abstract

The dynamic mechanical properties of polymeric composites composed of poly (methyl methacrylate) continuous-phase and various inclusion types of heterocoagulated composite particles were investigated in order to relate them to the morphology of shell region of composite particles. Using the heterocoagulation process, large particles were encapsulated with various types of small particles: (1) conventional linear-type polymer particles; (2) crosslinked polymer particles; and (3) reactive polymer particles capable of forming crosslinked structure, whereby the interfacial properties of the composite become modified. These composite particles were subsequently annealed to form continuous shell regions and then mixed with matrix particles. It is shown that chain diffusion movement of the small particles having different chain characteristics influences the network formation at the interfacial shell region. The ability of maintaining interfacial domain structure depends on the degree of network formation.
