High-molecular polymer reaction mechanisms and polymeric control methods
The polymer reaction is an important chemical reaction used to synthesize various materials of high molecules. Understanding the aggregation
The mechanism of reaction and the method of controlling aggregation are important for the preparation and performance control of high molecular materials。
I. High-molecular polymer reaction mechanisms
High-molecular polymerization is the process of connecting a monomer molecule to a high-growth chain molecule via a co-price key. Convergence reverse
The structure can be divided into the following categories: free radical polymerization, anion polymerization, anion polymerization and ion exchange polymerization
Type。
Free-based polymers are the most common polymer-reacting machines, in which monomer molecules act as free-based triggers
Generate free radicals, then react with single molecules, create new free radicals, and repeat this
Process, eventually forming a high molecular chain. Free-based polymers have the advantage of speed of reaction, wide application, etc., and should be broadly based
For polymer synthesis。
Anion fusion means the generation of a negative ion free radical by an anion-induced agent, which reacts with a monomer molecule. Fan
The process of forming a new free base of negative ion, eventually forming a high molecular chain. The acoustic condensation reaction is slow, but it is
To synthesize high-purity molecular material。
Acoustic polymers produce positive ion free radicals from an anion-induced agent, responding to monomer molecules
New positive ion free radicals, culminating in high molecular chains. Anion aggregation applies to specific monomers and quotations
Episode, often used to synthesize high-molecular materials containing positive charge。
Ion exchange polymers cause a single molecule to collide by the charge attraction between anion and anion
The process of generating high molecular chains. Ion exchange polymers can be used to synthesize high-molecule materials with special function
Like ion exchange resin。
Ii. Methodology of corporation
Aggregation refers to the number of repetitions of single molecules in high molecular chains and is important for measuring the chain length of high molecular material
Indicators. The control of polymerization regulates the physical and chemical properties of high molecular materials。
