Abstract

Bu bulusta söz konusu olan (co) polyesterlerin dolaysiz kimyasal degiskesi islemidir. Islem sirasinda genel formül (I) ve (II)'nin en az bir monomer bilesimi kullanilir (I) G R (II) G R G-en az bir adet polyester özelligi olmayan hetero atoma sahip, P;N ve S gruplarindan seçilmis kimyasal gurup R- asagidaki tiplerde reaktif baglanma * 4,7 ya da 8'li bir halkada lakton veya * siklik anhidrit veya * epoksit kendisini tekrarlayan polyester birimleriyle iliskili olarak %10 mole kadar kullanilmasi gerekli bir miktar içinde; lüzumu halinde polyester veya polyester eriyigine belli dozda katilir; gaz alisverisine kapali ve kullanilan bilesimlerin buhar basincindan daha yüksek bir basinc altinda kalan sistem olarak, ergimiyle meydana gelen veya zaten mevcut olan polyester er8iyiliklerine en az 260 C isida karistirilir. Kimyasal gurup reaktif olarak polyestere ilave edilir, yani baglanir ve kimyasal olarak degiskeye ugramis polyester erigiyi 30 dakikadan az olan tam bir (DEVAMI VAR)In this invention, (co) is the direct chemical change of polyesters. During the process, at least one monomer combination of general formulas (I) and (II) is used. (I) GR (II) GR G-chemical group R, selected from P and N and S groups with at least one non-polyester property. - Reactive bonding of the following types * In an amount of 4.7 or 8 rings, up to 10% mole associated with lactone or * cyclic anhydride or * epoxide itself repeating polyester units; if necessary, it is added to polyester or polyester solution in a certain dose; As a system that is closed to gas shopping and is under a higher pressure than the vapor pressure of the components used, it is mixed with at least 260 ° C to the polyester melts that occur by melting or already exist. The chemical group is reactively added to the polyester, i.e., bound and chemically degraded polyester melt in a complete (less than 30 minutes)
