Abstract
การประดิษฐ์นี้เกี่ยวกับกรรมวิธีสำหรับการผลิตพอลิยูเรเธน โดยการทำปฏิกิริยา a) พอลิไอโซไซยาเนทกับ b) สารประกอบที่มีอย่างน้อยสองไฮโดรเจนอะตอม ซึ่งไวต่อปฏิกิริยาต่อ หมู่ไอโซไซยาเนท, ซึ่งสารประกอบ b) ที่มีอย่างน้อยสองไฮโดรเจนอะตอม ซึ่งไวต่อปฏิกิริยาต่อหมู่ไอโซไซยาเนท ประกอบรวมด้วยอย่างน้อยหนึ่งพอลิอีเธอร์แอลกอฮอล์ b1) ซึ่งได้เตรียมโดยปฏิกิริยาของแอรอแมทิค แอมีน bla) ด้วยโพรพิลีนออกไซด์ โดยใช้แอมีน blb) ซึ่งแตกต่างจาก bla) เป็นตัวเร่งปฏิกิริยา This invention is about a process for the production of polyurethane. By reacting a) polyisocyanate with b) a compound containing at least two hydrogen atoms. Sensitive to Isocyanate group, in which compound b) has at least two hydrogen atoms Which is susceptible to reaction to isocyanate groups Consisted of at least one polyether alcohol (b1) which was prepared by the reaction of aramatic amine bla) with propylene oxide using blb amine), unlike bla) as Catalyst
