POE (Polyolefin Elastomer) is a type of ethylene/ α- A random copolymer of two monomers of olefins, also known as ethylene elastomer. POE has excellent comprehensive performance with the dual characteristics of plastic and rubber, and is therefore widely used in automotive components, wires and cables, impact modifiers, pipes, films and other fields. This article will introduce the manufacturing methods of POE

1、 Catalyst preparation 

Catalysts are a crucial component of the POE manufacturing process, typically using metallocene catalysts. The preparation of metallocene catalysts requires the use of methylaluminoxane (MAO) and metallocene compounds. Mix an appropriate amount of metallocene compounds with methylaluminoxane, stir well, and obtain a catalyst solution

2、 Polymerization reaction 

In the polymerization reactor, the catalyst solution, ethylene, and α- Olefin monomers are added in a certain proportion, then heated to a certain temperature and pressure is adjusted to allow the monomers to undergo polymerization reaction under the action of a catalyst. During the polymerization process, it is necessary to control the reaction temperature and pressure to ensure that the molecular weight and molecular weight distribution of the product meet the requirements

3、 After the polymerization reaction is completed, the product needs to be degassed and devolatilized to remove unreacted monomers and catalyst residues. This process usually involves vacuum degassing or steam blowing

4、 Granulation and packaging 

The POE products after degassing and devolatilization treatment need to be granulated to obtain particles of certain shape and size. During the granulation process, attention should be paid to controlling the particle size and distribution to avoid affecting the processing and usage performance of the product. After granulation is completed, the product is packaged for transportation and storage

In summary, the manufacturing method of POE requires strict control of each process step to ensure the quality and performance of the product. Meanwhile, for different application scenarios, it is necessary to optimize and adjust parameters such as catalysts, monomer ratios, and polymerization conditions to obtain products that meet different needs.
