Chain transfer agent - Names and Identifiers
Chain transfer agent - Introduction
Chain transfer agent refers to a compound that regulates the length of the polymeric molecular chain during the polymerization reaction. It can change the length of the polymerized molecular chain by reacting with the polymer chain and transferring the intermediate radicals formed in the polymerization reaction to itself.
The nature of the chain transfer agent is usually stable and can effectively accept free radicals in the polymerization reaction and react with the polymer chain. Common Chain transfer agents include compounds such as sulfides, oxides, halogenated alkanes, and silanes.
The main purpose of Chain transfer agent is to control the molecular weight and molecular weight distribution of polymers in polymerization reactions. By adding an appropriate amount of Chain transfer agent, the rate of the polymerization reaction and the molecular chain length of the polymer can be adjusted to achieve the desired polymer properties. Chain transfer agent can also be used to prepare copolymers, control polymer morphology and cure polymers.
The preparation method of Chain transfer agent can be synthesized or purchased. Some common Chain transfer agents can be synthesized by synthetic chemical methods, while other common Chain transfer agents such as sulfides can be obtained commercially.
You need to pay attention to security when using Chain transfer agent. Chain transfer agent may be toxic or irritating, so personal protective equipment such as gloves and goggles should be worn during operation, and good ventilation should be maintained. In addition, contact with the skin and inhalation of the gas of the Chain transfer agent should be avoided, and the relevant safe operation regulations should be followed when using and storing the Chain transfer agent.
