    摘要: An olefin-metathesis catalyst is provided. The olefin-metathesis catalyst includes a magnetic carrier, a polymer having formula (I) grafted on the magnetic carrier, and a ruthenium complex loaded on the polymer. A method for preparing low-molecular-weight nitrile butadiene rubber is also provided. In formula (I), one of X, Y and Z is nitrogen atom, the others are carbon atoms, R1 and R2, independently, include hydrogen, ester group, C1-10 alkyl group, C3-8 cycloalkyl group, 4-ring to 8-ring heterocycloalkyl or C6-10 aryl group, R3 includes hydrogen or C1-10 alkyl group, m ranges from 10 to 2,000, and n ranges from 0 to 1,000.

    摘要: 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.
