摘要： A continuous operation method is employed for the microwave high-temperature pyrolysis of a solid material containing an organic matter. The method includes the steps of mixing a solid material containing an organic matter with a liquid organic medium; transferring the obtained mixture to a microwave field; and in the microwave field, continuously contacting the mixture with a strong wave absorption material in an inert atmosphere or in vacuum. The strong wave absorption material continuously generates a high temperature under a microwave such that the solid material containing an organic matter and the liquid organic medium are continuously pyrolyzed to implement a continuous operation.

摘要： A spherical carrier for olefin polymerization catalysts has at least one magnesium-containing compound having a structure represented by formula (1). The spherical carrier has a relatively good particle morphology, and substantially no abnormally morphological particles will appear. A method for preparing the spherical carrier can be used to prepare a carrier having a small particle size and greatly expands the particle size range of the preparable carrier. When the catalyst prepared by using the carrier is used for olefin polymerization, polymerization activity is good, substantially no abnormally morphological material is present, and hydrogen response is good.

The xylene solubles content of the copolymer is less than or equal to 4 wt %, and preferably less than or equal to 3 wt %. The propylene-butene copolymer is substantially free of fraction having a molecular weight lower than 1000. The copolymer has a melt flow index of greater than or equal to 20 g/10 min as measured at 230° C. under a load of 2.16 kg. The propylene-butene copolymer has a high melt flow index and few xylene solubles, and does not contain a phthalate-type plasticizer, and can be used in fields such as food and medical and health services.

摘要： A super-wet surface is a polypropylene surface, on which a hydrophilic side group is grafted, having a micro-nano structure. The super-wet surface is at least super-hydrophilic and does not contain an initiator residue. The super-wet surface is prepared by grafting, in the absence of an initiator, by means of microwave irradiation, a monomer for forming a side group, on the polypropylene surface, as a grafting base, having a micro-nano structure. In the preparation of the super-wet surface, the molecular weight of polypropylene does not decrease after grafting, there is no residual monomer or initiator residue, and the super-wetting effect of the obtained surface is lasting and stable. The super-wet surface can be used in bonding, spraying, oil-water separation, water treatment, biology, medicine and energy fields.

摘要： A halogen-containing compound as shown in a formula I can be used as a ligand for an ethylene oligomerization catalyst composition. The ethylene oligomerization catalyst composition containing the halogen-containing compound can be used to catalyze ethylene oligomerization, trimerization and tetramerization reactions. As a ligand of a catalyst for ethylene oligomerization, a fluoropolymer can effectively improve the catalytic performance of a catalyst system, and particularly exhibits improved activity and selectivity in an ethylene oligomerization reaction.
