  • Patent number: 8013060
    Abstract: The present invention relates to a method for concentrating organic silicate polymer solution, and more precisely, a method for concentrating organic silicate polymer solution by distillation which is characterized by remarkably reduced distillation time realized by the short-term continuous distillation at low temperature under low pressure, minimized physical property changes attributed to the inhibition of the heat-induced reaction by making the solution pass through the thin film evaporator shortly, concentration without cake generation, and easy manipulation with high capacity, making the method highly economical.

  • Publication number: 20070299226
    Abstract: The present invention relates to a method for preparing an acrylic ester polymer syrup by bulk polymerization, and more particularly, to a method for preparing an acrylic ester polymer syrup, which comprises the steps of: supplying a monomer solution and an initiator solution to a monomer solution reservoir and an initiator solution reservoir, respectively; supplying the monomer solution and the initiator solution to a complete-mixing type continuous reactor, while maintaining the dissolved oxygen in the monomer solution reservoir and the initiator solution reservoir at 0.0001 to 3 ppm, separately or after mixing prior to the supply; and performing bulk polymerization continuously while maintaining the solution mixture supplied to the continuous reactor at 70 to 150 ° C. and 1 to 10 atm, with a mean residence time of 30 to 240 minutes.
