The present invention relates to a composition for manufacturing a carboxylic group-containing polymer and a carboxylic group-containing polymer manufactured by using the same. More particularly, the present invention relates to a composition for manufacturing a carboxylic group-containing polymer comprising an allyl monomer having a long chain of a hydrophilic part containing alkylene oxide and a side chain of a hydrophobic part containing fatty acid ester as a dispersion promoter; a vinyl group-containing unsaturated carboxylic acid; a vinyl group-containing crosslinking agent; and a radical polymerization initiator, and a carboxylic group-containing polymer manufactured by using the same wherein the polymer can be dispersed in water without stirring, its dispersion solution has low viscosity, and its neutralized viscous solution obtained by alkali neutralization has high viscosity and transparency. Therefore, the carboxylic group-containing polymer of the present invention can be effectively used in the fields of a thickener and a dispersion stabilizer for an emulsion, a suspension and the like.

Disclosed is an optical member for use in liquid crystal displays, which can correct the light path and can minimize the loss of light, so that light in a wider angular range can be collected forwards. Even when a distance between the optical member and a light source is shortened, the optical member can exhibit good hiding performance and prevent deformation caused by heat. Upon expansion and shrinkage, the optical member is not scratched and does not generate noise at a portion in contact with a support pin.

The present invention provides a stent that allows a simple surgical operation for affected parts of a lumen in a human body, and particularly reduces a medical side effect by contact or friction between the inside of the lumen and the outside of the stent when the stent is removed from the lumen. The stent includes a cylindrical wire structure having an internal passage and wires that are bent along the internal passage to have peaks and valleys, and a cover film that covers the wire structure. In particular, the cover film covers the wires such that the wires are embedded at the outside of the wire structure and exposed at the inside.

摘要:
A bumper step for a heavy-duty truck includes a main bracket that is provided on a front lower portion of a vehicle. The lower end of a first step is hinged to the main bracket such that the first step is rotatable and deployable downwards, and the first step is fixed in a deployed position. A second step is provided behind the first step. The upper end of the second step is hinged to the main bracket such that the second step is rotatable and deployable upwards. The second step is fixed in position above the first step.
