    摘要： A distributing plate for a high-viscosity fluid which distributes and discharges the high-viscosity fluid is disclosed. The distributing plate may comprise: a flat top surface; a side surface having a diameter that increases downwardly from the upper surface; a plurality of inner holes arranged on the upper surface along a plurality of first imaginary concentric circles; and a plurality of outer holes arranged on the side surface along a plurality of second imaginary concentric circles. The ratio of the area of each inner hole to the area of each outer hole may be 1.2-1.4.
    In addition, an apparatus of distributing a high-viscosity fluid including the distributing plate for a high-viscosity fluid is disclosed.

    摘要： The present invention relates to a method of preparing a polymer, which includes: adding an alkyl-substituted aromatic vinyl-based monomer and a vinyl cyanide-based monomer to a reactor and initiating polymerization; and performing polymerization while continuously adding the alkyl-substituted aromatic vinyl-based monomer and a multifunctional initiator to the reactor, wherein the continuous addition of the alkyl-substituted aromatic vinyl-based monomer and the multifunctional initiator is initiated when a polymerization conversion rate is 10 to 30%, and the continuous addition of the alkyl-substituted aromatic vinyl-based monomer and the multifunctional initiator is terminated when a polymerization conversion rate is 70 to 80%.
