Abstract: A reclaiming agent is formed by grafting thiol groups onto styrene-butadiene rubber (SBR). The reclaiming agent has a weight average molecular weight of 1000 to 120000, which can be a random copolymer or a block copolymer. 100 parts by weight of styrene-butadiene rubber can be reacted with 0.1 to 50 parts by weight of the reclaiming agent to form a reclaimed rubber.
