Abstract: An extended film and a manufacturing method thereof are provided. The extended film includes a poly(lactic acid) and a block copolymer, wherein the block polymer includes a first block, a second block and a third block that connected with each other by chemical bonds. The extended film is formed by steps of mixing poly(lactic acid) and the block copolymer to form a mixture, compressing the mixture to form a board body and extending the board body to form an extended film, thereby forming an extended film having properties of high thermal-resistance and high transparency, the film thus obtained is applicable for packaging use.

Abstract: A depolymerizer is formed by grafting thiol groups on parts of the double bonds of a polymer of linear conjugated diene monomer. The linear conjugated diene monomer can be 1,3-butadiene, isoprene, 1,3-pentadiene, 2,3-dimethyl-1,3-butadiene, 2-methyl-1,3-pentadiene, 2,3-dimethyl-1,3-pentadiene, 2-phenyl-1,3-butadiene, or 4,5-diethyl-1,3-octadiene. The depolymerizer has a weight average molecular weight of 1000 to 400000.

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.
