ELASTOMERS WITH EXCEPTIONAL ELONGATION |
摘要 |
Nanocomposites exhibiting elongation exceeding about 2000%, elastic recovery, and tensile strength exceeding 2.5 MPa are described. A method these elastomers involves performing a catalyzed step growth polymerization of a heterobifunctional siloxane macromonomer compounded with at least about 15 wt % surface passivated silica nanoparticles. The macromonomer has a degree of polymerization of at least about 40 and the silica nanoparticles have nominal diameters of less than about 50 nm. |
