摘要： The present utility model relates to a multifunctional packing box. In which the peripheral connecting positions of the box walls are connected by the ".OMEGA." type hinges, and there are locking clips fixed in the upper and lower ends of the hinges. The peripheral edges of the box cover and box bottom are fixed by the grooved metal rim, and there are locking teeth fixed inside the box cover and box bottom. When in use, the box body is pushed off, and the upper and lower edges of the box body are inserted into the metal grooves of the box cover and box bottom which are buckled, the locking clips with the locking teeth are meshed and locked. Once the box cover and box bottom are opened, then some traces will remain on the box cover which are not recoverable. In the mean time, for transporting the empty, the box body can be closed in randomly from left or right. This packing box is convenient to use and has a good safety feature, so that it is an ideal substitute for the current packing boxes.

摘要： The invention discloses one method of producing polyether polymer dispersant and polyether polymer, wherein the dispersant is a copolymer macromolecule prepared by the propylene oxide or ethylene oxide with an average molecular weight of 6000 to 20000, with containing at least one benzene ring group and one polymerizable carbon-carbon double or triple bond polymer. The preparation method of the dispersant is: synthesizing a basic polyether polyol, adding a cyclic dicarboxylic anhydride into the polyether polyol, then the polyether polyol is reacted with an epoxy compound with the polymerizable double bond, and capping with an epoxy compound to obtain the dispersant; preparing the polymer polyol by the basic polyol, an unsaturated vinyl monomer styrene and acrylonitrile, a polymerization initiator, the dispersant and an optional chain transfer agent; the basic polyether is a polyether polyol with a functionality of 3 to 8.
