Factors affecting the polymerization degree of paste resins
Thread Content
Factors affecting the polymerization degree of resin paste: this degree decreases in winter. Various reasons have been sought, but no cause has yet been identified. The polymerization degree is generally related to factors such as polymerization temperature, reaction time, raw materials used for polymerization, and testing methods. I hope everyone can discuss this to see if any insights can be gained
What process do you use for the paste resin? The average molecular weight obtained by emulsion polymerization is similar to that of suspension polymerization; it is also transferred to the monomer chains, and the degree of polymerization is related to the polymerization temperature ； Emulsion polymerization takes place within micelles, with each micelle containing only one free radical. In emulsion polymerization, the reaction rate increases as the number of particles increases, while the degree of polymerization decreases. As the degree of polymerization decreases, in addition to checking the quality of the monomers (acetylene, oxygen, and high-boiling substances) and the polymerization temperature, it is also necessary to examine the amount of emulsifier added as well as the rate of the polymerization reaction.
Does the water-oil ratio have an effect on the degree of polymerization?
The cause has been identified as an increase in acetylene content in the monomer, which affects performance
