Abstract: A grafted polypropylene resin is prepared by a grafting reaction of a polar monomer capable of absorbing microwave so as to raise its temperature in a microwave field to more than 200° C. and a solid polypropylene resin using microwave irradiation without adding an initiator. The polar grafted polypropylene resin that does not contain initiator residues and does not have a significant reduction in molecular mass compared with a resin before grafting is obtained.

Abstract: 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.

Abstract: This application relates to a cover assembly of a secondary battery. The cover assembly includes a cover plate with an air hole; a blocker inserted into and blocking the air hole; a sealing member disposed between the blocker and the cover plate configured to seal a gap between the blocker and the cover plate; and a fastener disposed inside the air hole. The fastener is connected to the cover plate, the blocker is connected to the cover plate through the fastener. The fastener is configured to deform in response to a temperature rise, so that the blocker stops blocking the air hole. The blocker stops blocking the air hole as a temperature inside a housing rises, to discharge gas from the housing through the air hole. In this way, the secondary battery can be prevented from an explosion, while partial heat is taken away through gas discharge.

Abstract: A convertible reusable diaper is provided, comprising an outer cover, a barrier panel portion, and at least one of a liner portion and an absorption portion. One or more first fastener members are attachable to at least one of the outer cover portion and the barrier panel portion. One or more second fastener members are attachable to at least one of the liner portion and the absorption portion, wherein at least one of the second fastener members is cooperatively engaged with at least one of the first fastener members, thereby allowing at least part of at least one of the liner portion and the absorption portion to be detachable to the outer cover portion. One or more hole-openings are formed on the barrier panel portion, thereby allowing engagement between the first and the second fastener members.

Abstract: A convertible reusable diaper is provided, comprised of an outer cover portion, a liner portion, and a detachable absorption portion. The outer cover portion may generally include barrier panels attached at both the front and rear regions of the outer cover portion to form interior pockets. A plurality of fastenable tabs attached to hole-openings at the barrier panels affixes the liner portion or the detachable absorption portion in place. The hole-openings allow the passage of the fastenable tabs through the barrier panels. Both the liner portion and the detachable absorption portion include fastener members inter-engaged with the corresponding fastener members located at the fastenable tabs to allow the liner portion or the detachable absorption portion to be removably affixed to the outer cover portion. Numerous options for affixing the insert portion and the detachable absorption portion allow conversion to different diaper designs.

Abstract: A process for preparing a supported metallocene/aluminoxane solid catalyst comprises preparing a water-in-oil emulsion of water and an inert solvent by using an emulsifier, adding dropwise the emulsion to a solution of an organoaluminium compound in an inert solvent to carry out the reaction to obtain a suspension of the particulate aluminoxane, followed by adding a solution of a metallocene to the above suspension to support the metallocene on the aluminoxane. The solid catalyst thus obtained can be used in the polymerization and copolymerization of olefins. Polymerization can be carried out by slurry polymerization, bulk polymerization, gas phase polymerization, etc.
