Abstract
Polymer nanoparticles with cross-linked core and PBA/PS double-shell were synthesized and their baroplastic properties were characterized. PBA/PS, the inner and outer shell with cross-linked core consisting of St and DVB were synthesized by three-stage emulsion polymerization. The obtained materials exhibited pressure-induced mixing of their components and could be processed at 25 C by compression molding which means there was no effect of the presence of cross-linked core. Interestingly, the Young’s modulus of molded objects has found to be affected strongly by the size of double-shell nanoparticles. Furthermore, the molded object of higher PBA content was successfully recycled 5 times at 25 C and showed 0.55 MPa of modulus and 1.81 MPa of strength at break.
