Copolymers containing POSSPolyhedral Oligomeric Silsesquiaxane Generally have higher mechanical and thermal properties than polymers without POSS. The microstructure that lends to these increase may be caused by POSS nanoparticle units or aggregates of these units to farm larger POSS clusters. To help define the microstructure of the addition copolymers, the POSS macromer and organic monomer reactivity ratios r1 and r2 need to be known. Alternating Copolymerization r1r2O, Block Copolymerization r11, r21, Random Copolymerization r1r21.
