| titleOfInvention | Emulsion polymerization of carboxylated styrene-butadiene latex by using tert-dodecylmecaptan as a chain transfer agent |
| abstract | The present invention relates to an emulsion polymerization method for controlling gel content by using styrene and butadiene as main monomers and tertiary-dodecyl mercaptan as a molecular weight regulator, and more specifically, in the initial polymerization step, the entire monomer of styrene and butadiene 10 to 20% by weight and a small amount of itaconic acid monomer, acrylic acid monomer, emulsifier, initiator and reducing agent are added and reacted, and 80 to 90% by weight of all the styrene and butadiene monomers and a small amount of acrylic acid monomer, emulsifier and In the polymerization method of carboxy-modified styrene-butadiene-based latex, characterized in that the polymerization temperature is raised stepwise at 60 ° C, 70 ° C, 75 ° C and 80 ° C by using tertiary-dodecylmercaptan as a molecular weight regulator. It is about. This manufacturing method facilitates process control by reducing the influence of initial polymerization on the gel content of the whole latex, and the gel content can be increased only by the input by dynamic control of tertiary-dodecyl mercaptan in the polymerization polymerization by continuous injection. It is easy to control, and the polymerization stability is greatly improved, which reduces production cost and improves productivity. |
