Pentaerythritol tetrakis ester

Transesterification reactions between the methyl propionate and various alcohols produce another family of stabili2ers. Stearyl alcohol yields octadecyl 3-(3,5-di-/ f2 -butyl-4-hydroxyphenyl)propionate (27) (16), pentaerythritol gives the tetrakis ester (28) (17), and trishy dr oxyethyl isocyanurate gives (29) (18). 

A typical formulation for a polypropylene (PP) film used for wrapping biscuits would be PP 100 pph pentaerythritol tetrakis[3-(3,5-di-tertbutyl-4-hydroxyphenyl) propionate] 0.1 pph phosphorous acid, tris(2,4-di-tert-butylphenyl)ester 0.1 pph emcamide 0.05 pph. Nucleators, such as substituted benzylidene sorbitols, can be added to improve the clarity of PP and LDPE (see Eig. 10.4). Oriented polypropylene (OPP) films are also available where a higher transparency is required with improved strength.
