Poly[oxy(ethylthiomethyl) ethylene] (ETE) was prepared from poly[oxy (chloromethyl)ethylene] (CE) by reaction with sodium ethanethiolate. Sulfoxide and sulfone analogues were synthesized by oxidation of the poly[oxy(ethylthiomethyl) ethylene]. By changing the chloromethyl/sodium ethanethiolate rati

Butyl acrylate colloids were obtained by codeposition at 77 K of the monomer with several metals such as Pd, Au, Ag, Cu, Zn, Cd, Ga, In, Ge, Sn, Sb, and Bi. The colloids were polymerized with different amounts of an initiator (AIBN) at 65Β°C for 0.5 h and a wide range of viscosity-average molecular w
