  • High Strength Ultra-thin Biodegradable Film and Preparation Method Thereof
    Publication number: 20220332888
    Abstract: A biodegradable film is prepared from a composition that includes a copolyester obtained by extrusion reaction of a branched aliphatic-aromatic copolyester derived from monomer a, monomer b, monomer c and monomer d with an organic peroxide. The film can be completely degraded into small molecular products such as carbon dioxide, water and the like under natural or composting conditions. Moreover, the film can be prepared having a thickness of 4-50 ?m as required, and its mechanical properties can reach the same level as or even better than those of LDPE film.

  • Catalyst component for ethylene polymerization, preparation thereof, and a catalyst comprising the catalyst component
    Patent number: 8268945
    Abstract: A catalyst component for ethylene polymerization, comprising an organic silicon compound of the formula (I), below wherein R1 is chosen from C3-C20 aliphatic hydrocarbyl groups, and is substituted with at least one substituent chosen from halogens, C1-C6 acyloxy groups, epoxy, amino, C1-C6 alkylamino groups, di(C1-C6 alkyl)amino groups, C1-C6 alkoxy groups, and oxo group; R2, R3 and R4, which may be the same or different, are each chosen from C1-C10 aliphatic hydrocarbyl, C3-C10 alicyclic hydrocarbyl, C6-C10 aryl, C7-C10 aralkyl, and C7-C10 alkaryl groups. A process for preparing the catalyst component and an active catalyst comprising the catalyst component and useful in polymerization, such as ethylene polymerization.
