* Change the phosphite, which inhibits color formation by alleviating the workload on the phenolic.
For the second method, tris(nonylphenyl) phosphite (TNPP) was used as a stabilizer during testing.
Unreacted phosphite in the polymer after processing continues to destroy hydroperoxides throughout the life of the polymer, or of the additive.
The stabilizer is also "future-proof," adds Jakupca, given that it has forward-looking characteristics in its composition: unlike traditional phosphite heat stabilizers, it's polymeric, so it shows very low migration through the bulk polymer.
This 20-page, four-color brochure describes the company's high performance additives, including antioxidants for heat stabilization and property maintenance, lubricant additives for straight oils, soluble oils and synthetic coolants, high performance specialty additives for paints, coatings, cleaners and lubricants, alkylphenol building blocks for high performance chemicals, flame retardants, metallic stearates for coatings, cleaners and lubricants, advanced phosphite ester technology and more.
The occurrence of transesterification reactions in poly(ethylene terephthalate) (PET)/poly(ethylene naphthalate) (PEN) blends prepared in presence of triphenyl phosphite (TPP) was investigated.

In response, in one example, Addivant announced this year that its Weston[R] 705 liquid antioxidant, a nonylphenol-free phosphite additive, received food-contact approval from the U.S.
Dover Chemical, Dover, Ohio (doverchem.com) unveiled its newest, "green" Doverphos LGP-11, a proprietary, high-molecular-weight liquid phosphite developed as a replacement for workhorse phosphite TNPP, particularly for polyolefin packaging where purity is an issue.
