Information

Ethylene/propylene random copolymers are prepared by the simultaneous polymerization of ethylene molecules and propylene molecules in the same reactor as that used for the production of PP homopolymers. Ethylene molecules are smaller than propylene molecules and react faster (about ten times more reactive) than propylene. This weakens the stereospecificity of the catalyst and increases the activity, resulting in an increase in the innate amount of atactic polypropylene. In order to reduce the generation of this random species, it is necessary to reduce the reaction temperature, thereby reducing the activity of the catalyst, and reducing the content of random isomers in the final product to obtain a product with more balanced properties.

The melting point reduction of the copolymer is directly related to the ethylene content. The copolymers have been reported to have melting points as low as 152°F at 7% ethylene. The effect of X3 content on the melting point of the copolymer was greater than that of the gene content of Er and higher. It also depends on the catalyst itself, and its ability to bind ethylene with X3 groups instead of X5 groups.
