Abstract
กรรมวิธีสำหรับการผลิตพอลิบิวทะไดอีน หรือพอลไอโซพรีนในเครื่องทำปฏิกิริยา ชนิดแก๊ส เฟส โดยการบรรจุกระแสของโมโนเมอร์ชนิดบิวทะไดอีนหรือไอโซพรีนและแก๊สเฉื่อย ที่เลือกได้อย่างต่อเนื่อง เข้าไปในแถบการเกิดพอลิเมอร์ขณะที่ทำการรักษาอุณหภูมิภายในแถบ การเกิดพอลิเมอร์ให้ต่ำกว่าอุณหภูมิจุดน้ำค้าง ( dew point ) ของโมโนเมอร์ที่มีอยู่ในแถบการ เกิดพอลิเมอร์โดยมีตัวเร่งปฏิกิริยาที่เป็นแรร์เอิร์ชอยู่ด้วย และที่มีวัสดุชนิดอนุภาคที่เฉื่อยอยู่ด้วย Process for the production of polybutadiene Or Pall isoprene in gas-phase reactors by filling the current of butadiene monomer or isoprene and inert gas. Which can be continuously selected Into the polymerization band while maintaining the temperature inside the band. Polymerization below the dew point temperature of existing monomers in the A polymer is formed with a rare earth catalyst. And containing inert particle materials
