INITIATING SYSTEM FOR SOLID POLYESTER GRANULE MANUFACTURE |
摘要 |
The invention relates to the use of a diacyl peroxide in combination with an aromatic amine of formula (I) where R1 is C1-C20 alkyl having at least one hydroxy substituent or -(CH'CHR'-O)nH where n is 1 to 10 and each R' is independently selected from H and C1-C3 alkyl; R2 is C1-C20 alkyl optionally substituted with one or more hydroxy groups, or -(CHR'CHR'-O)nH where n=1 to 10; and each R is independently selected from H and C1-C3 alkyl; and Ar is an optionally substituted aryl group; as a redox initiating system in a process for the manufacture of polyester granules by suspension polymerisation. This invention also relates to a process for preparing solid polyester granules using such a redox initiating system. |
