The present disclosure relates to an internally plasticized polyvinyl chloride resin and a process for preparation thereof. The internally plasticized polyvinyl chloride resin comprises a polyvinyl chloride (PVC) resin covalently bonded to at least one plasticizer. The process is simple and economical and provides internally plasticized PVC with enhanced flexibility, and improved characteristics than conventional PVC resin.

The present invention provides a dispersion stabilizer for suspension polymerization that, when used for suspension polymerization of a vinyl compound, provides excellent polymerization stability, and can produce a vinyl polymer having a reduced number of coarse particles, and a reduced number of fisheyes when molded into a sheet form. The present invention also provides a method therewith. The present invention relates to a dispersion stabilizer for suspension polymerization of a vinyl compound, the dispersion stabilizer comprising a vinyl alcohol polymer (A) having a viscosity-average degree of polymerization of more than 400 and less than 1,000, a degree of saponification of more than 67 mol % and less than 78 mol %, 0.02 mol % to 1.0 mol % of a group having an ethylenic double bond in its side chain, and an absorbance (x) at 280 nm of more than 0.17 and less than 0.65 in an ultraviolet absorption spectrum of a 0.1 mass % aqueous solution.

The present invention relates to the technical field of polymer spectral probes, and particularly to a perchloroethylene derivative and use thereof. The perchloroethylene derivative is prepared by reacting a compound A and a perchloroethylene resin. According to the present invention, the fluorescent polymer can be used as a high-selectivity and high-sensitivity enhanced colorimetric and fluorescent polymer probe for Fe.sup.3+ and Cr.sup.3+ As compared with the organic small molecule spectral probe, the polymer spectral probe has improved mechanical property, film forming property and excellent recyclability, and thus has a strong practicability.
