Beschreibung
Zusammenfassung:	Disclosed are a novel chain transfer agent having a trichloromethyl functional group bonded at an end thereof, an end-modified styrene-butadiene copolymer prepared by using the chain transfer agent, and an organic-inorganic composite obtained by mixing the end-modified styrene-butadiene copolymer with silica. The disclosed end-modified styrene-butadiene copolymer has a high affinity with silica because its end is modified with a hydrophilic chain transfer agent. Thus, the organic-inorganic composite including the mixture of the copolymer with silica is useful as a material for the manufacture of rubber products such as a tire, a sole, a rubber hose, or a rubber belt.
