Polymer devolatilization
Thread Content
I’m a complete novice in the field of chemistry. Seeking experience in polymer devolatilization techniques. The polymer obtained after the polymerization reaction contains residual monomers; what are the common methods used for degassing? Screw devolatilization? Devaporator?
Let me recommend a book to you: \"Polymer Devolatilization\" by R.J. Albalak from the United States, translated by Zhao Xutao, Gong Guangbi, Gu Yusheng, and others
Generally, there are several methods: 1. Removing residual monomers during the polymer production stage, using heating or vacuum extraction for recovery； 2. During the polymer processing stage, vacuum is applied in the degassing section on the screw.
Volatile matter should generally be fine with heating and vacuuming.
I have found this book; thank you very much
Okay, I’ll get in touch with the screw manufacturer
Just because one can work on screw compressors doesn’t mean they can handle devolatilization
So, may I ask which manufacturers can do it?
A vacuum reduction device also needs to be added as well
