Dicyclohexyl terephthalate

Diphenyl sulfite decomposes PET immediately after its addition and lowered the degree of polymerization. Diphenylbenzene phosphite increased the degree of polymerization but 57% (calculated as P) of the added phosphite remained in PET, resulting in a lower softening point. Dicyclohexyl terephthalate lowered the degree of polymerization. 

The world-wide production of PA (excluding fibers) in 1997 was 1.6x10 t, with a 75 % use of casting processed materials. For food contact articles the following can be used as starting materials straight chain u -amino acids (C6-C12) and their lactams adipic acids, azelaic acids, sebacic acids, dodecane dicarboxylic acids and heptadecane-dicarboxylic acids salts with hexamethylenediamine isophthalic acid, bis(4-aminocy-clohexyl)-methane, 2,2-bis(4 -aminocyclohexyl)-propane, 3,3 -dimethyl-4,4 -diamino-dicyclohexyl-methane, terephthalic acid or its methylester, l,6-diamino-2,2,4-tri-methylhexane, 1,6-diamino-2,4,4-trimethylhexane, l-amino-3-amino-methyl-3,5,5-tri-methylhexane.
