Abstract: A microspheric ionomer having a cross-linked structure, a preparation method therefor, applications thereof, and a preparation system thereof. The ionomer comprises structure units A represented by formula (1), structure units B represented by formula (2), and a cross-linking structure provided by a cross-linking agent, M being separately selected from H, a metal cation, and a straight chain, a saturated alkyl of branched or ring-shaped C1-C20, R being H or a methyl; and metal cations are introduced to part of structure units A in the ionomer. The ionomer shows an outstanding effect on nucleation of PET, serves as a nucleating agent for PET modification, so as to obtain a corresponding PET composition.

Abstract: The present invention relates to an ultra-short distance projection lens with a refractive meridional image surface and a refractive sagittal image surface being isolated, including a display chip, a refractive lens group, and a rotationally symmetric reflector. The display chip undergoes imaging by the refractive lens group to form, between the refractive lens group and the rotationally symmetric reflector, a meridional intermediate image and a sagittal intermediate image that are isolated, wherein the two images undergo imaging by the rotationally symmetric reflector and astigmatism is eliminated on a screen, to form a clear picture. The present invention has a simple structure, a projection ratio 0.27 to 0.31, a magnification ratio 170 times to 220 times, and ultra-small distortion, has an optical structure that cancels out astigmatism, high resolution, very desirable tolerance, and relatively low mounting precision requirements on optical parts, and has a very high yield in mass production.

Abstract: The present invention provides a preparation method of a catalyst component for olefin polymerization, comprising firstly dissolving an anhydrous magnesium halide into a mixed solvent which comprises an oxygen-containing organic titanium compound, an organic epoxy compound, a hydroxy-containing compound, and an inert solvent, and does not comprise a phosphate compound, so as to form a magnesium halide solution; then mixing the magnesium halide solution with a halogen-containing compound to precipitate a solid, so as to obtain the catalyst component, wherein the halogen-containing compound comprises at least one selected from a group consisting of halogen and titanium-containing compounds, halogenated organic hydrocarbon compounds, acyl halide compounds, halogen and phosphorus-containing compounds, halogen and boron-containing compounds, halogenated organic aluminum compounds, and halogen and silicon-containing compounds.

Abstract: A magnesium halide solution is disclosed. The magnesium halide solution comprises a magnesium halide, an oxygen-containing organic titanium compound, a hydroxyl-containing compound, and an organic solvent. The magnesium halide solution further comprises an organic heterocyclic compound. The organic solvent is a hydrocarbon and/or a halogenated hydrocarbon. The organic heterocyclic compound is at least one selected from a group consisting of a sulphur-containing organic heterocyclic compound, a nitrogen-containing organic heterocyclic compound, and an organic epoxy compound. The magnesium halide solution has a good stability, and can be used for preparing a catalyst for olefin polymerization and copolymerization reactions. The raw material of the magnesium halide solution is cheap and easy to be obtained. The preparing method is easy to be performed and is environment-friendly.
