Title:
A PREPARATION METHOD OF SMALL PARTICLE SIZED POLYBUTADIENE LATEX USED FOR THE PRODUCTION OF ABS
Document Type and Number:
WIPO Patent Application WO/2006/039860
Kind Code:
A1
Abstract:
A preparation method of small particle sized polybutadiene latex used for the production of ABS is disclosed, which includes putting the components comprising 34.00-45.00 weight% butadiene, 0-6.0 weight% the second monomer, 52.11-63.13 weight% desalinized water, 0.12-0.22 weight% mercaptan(TDM), 0.80-2.60 weight% emulsifiers composed of potassium abietate and potassium oleate, into the same polymerization reactor, then heating the mixture of the components and stirring it at a temperature range of 60-75 . The reaction lasts for 9-12 hours under the atmospheric pressure and the conversion is higher than 97%. The method has the advantages such as higher conversion, shorter reaction period and lower latex viscosity. During the first stage of the reaction, more heat is released by increasing the reaction rate. When the conversion reaches 40-80%, the heat release rate of intermediate stage is depressed by decreasing the reaction temperature. When the conversion is higher than 80%, the reaction temperature reaches the highest. Thus, severe heat release is avoided. Moreover, the butadiene polymerization can be controlled steadily and the reaction period is shortened.
