✦ Synopsis

Beta-cyclodextrin

(BCD) has an accelerating rate on the platinum-catalyzed hydrosilylation reaction. The addition of triethoxysilane to styrene was 45% complete after 0.5 h at 50Β°C but in the presence of BCD the reaction was 100% complete after 0.5 h at 50Β°C. Other conditions were explored as well. The platinum-catalyzed reactions of triethoxysilane and triethylsilane to vinyltrimethylsilane were accelerated by the presence of BCD. Platinum catalysts studied were Karstedt's catalyst, a Pt" complex with divinyltetramethyldisiloxane (M"M") in xylene and Lamoreaux' catalyst, a mixture of Pt" and Pt'" complexes in octanol.

## Abstract The purpose of our research was to prepare nanoencapsulated PET textile materials, which would be used as odor carriers (underwear and bed sheets with aromatherapy activities) or would act as malodorous absorbers (absorption of cigarette smell). We grafted β‐cyclodextrin onto PET textil
