## Abstract The UV curing process in both air and nitrogen atmosphere for the highly branched polycarbosilane system was investigated by differential scanning photo calorimeter. The UV cured products were characterized by Fourierβtransform infrared spectrometry (FTIR). By comparison with the FTIR r

## Abstract A facile approach for synthesis of hyperbranched polycarbosilane from AB~2~ monomer via UVβactivated hydrosilylation is presented in this communication. The polymerization process was monitored using realβtime FTIR spectroscopy and the resulting hyperbranched polycarbosilanes were chara
## Abstract Liquid polycarbosilanes substituted by unsaturated groups were prepared by a oneβpot synthesis with Cl~2~Si(CH~3~)CH~2~Cl, Cl~3~SiCH~2~Cl, and CH~2~ο£ΎCHCH~2~Cl (or HCο£½CMgBr) as the starting materials. The asβreceived polycarbosilanes were characterized by gel permeation chromatography, F
