Chemists will ask multiple questions whenever they’re asked to create a recipe for a polymer emulsion for a specific application. In this two-part series, we’ll take a look at the four big questions that they ask in these situations. The first question a chemist will ask when designing a recipe for... read more
It is difficult to generalize. If one of the two polymers behaves as an elastomer and the other is a hard plastic at room temperature, the IPN formed may be either a reinforced rubber or an impact-resistant plastic, depending on the ratio of the two. And preparation conditions.The results of electro... read more
Generally, the second monomer, together with the cross-linking agent and initiator (or activator), are swelled into the already cross-linked polymer I, and the second monomer is polymerized in situ and cross-linked to form polymer II, so that the latter It is interspersed in the polymer I network. I... read more
The common problem of many manufacturers is that the flame retardant effect of the flame retardant is not obvious, and the flame retardancy is uneven. On the same board, some places have obvious flame retardancy, some places have poor flame retardancy effects, and some places are flame retardant. T... read more
Let’s start with a definition for polymerization itself.Polymerization, as a chemical reaction, may occur with solids, liquids, or gases. Since solid state reactions are slow, and since gas-phase reactions require high temperatures (which leads to instability when trying to achieve a high molecular... read more
