2、Classification of polyketone resin
Polyketone resin is mainly formed by the monomer containing ketone group through polymerization reaction, with high molecular weight and good rheological properties. According to the different monomer structure and polymerization method, polyketone resin can be divided into aliphatic polyketone, aromatic polyketone and other types.
-Aliphatic polyketones
The main feature of aliphatic polyketone is that the monomer structure does not contain aromatic rings, and its molecular chain is mainly composed of aliphatic ketone groups. Due to the high reactivity of aliphatic ketone group, aliphatic polyketone has good processing performance and chemical stability. In the industrial field, aliphatic polyketones are widely used in plastics, rubber, coatings and other fields, and have good application prospects.
-Aromatic polyketones
Aromatic polyketones are characterized by an aromatic ring in the monomer structure, and their molecular chains are mainly composed of aromatic ketone groups. Due to the high stability of the aromatic ketone group, aromatic polyketone has good heat resistance, corrosion resistance and wear resistance. In the field of high technology, aromatic polyketones are widely used in aerospace, electronics, optics and other fields, and have important practical value.
In addition, polyketone resins can be classified according to different production processes and molecular structures:
Classification according to production process
-Solution polymerization polyketone resin
Solution polymerization is a common production process, which is characterized by the fact that the polymerization reaction takes place in a solution. By controlling the type and concentration of the solvent and the conditions of the polymerization reaction, polyketone resins with different properties can be obtained.
-Suspension polymerization polyketone resin
Suspension polymerization involves suspending monomers in water and initiating the polymerization reaction through an initiator. This process can obtain granular polyketone resins with good fluidity and dispersibility.
-Emulsion polymerization polyketone resin
Emulsion polymerization is to emulsify the monomer in water and initiate the polymerization reaction by initiator. This process results in emulsion-like polyketone resins with good compatibility and stability.
-Microsphere polymerization polyketone resin
Microsphere polymerization is a new type of polymerization process, through the control of the polymerization reaction conditions, can be obtained with a microsphere structure of the polyketone resin. This kind of resin has high specific surface area and porosity, and has good adsorption and catalytic properties.
Classification according to molecular structure
-Linear polyketone resin
Linear polyketone resin has a simple linear molecular structure, with good fluidity and ductility. It is widely used in plastics, rubber and other fields.
-Branched Chain Polyketone Resins
Branched polyketone resin has a complex molecular structure, due to the existence of branched chains, its heat resistance, abrasion resistance and corrosion resistance has been significantly improved. Widely used in aerospace, automotive, electronics and other fields.
-Network Structure Polyketone Resin
Network Structure Polyketone Resin is to make the polyketone molecules form a three-dimensional network structure through cross-linking agent, which has high strength, high hardness and high abrasion resistance. It is widely used in coatings, adhesives and other fields.
-Gradient Structure Polyketone Resin
Gradient structure polyketone resin is through the control of polymerization reaction conditions, so that the molecular structure shows gradient distribution. This resin has excellent mechanical properties and fatigue resistance, and is used in high-performance composites and other fields.
