TLDR
In this paper, a process for increasing the whiteness of a movie was described, based on a movie made from a mixture of a stylized version of the Pymer blend and a deterministic version of it.Abstract:
A PROCESS FOR INCREASING THE WHITENESS OF A FILAMENT EXTRUDED FROM A POLYMER BLEND COMPRISED OF POLYESTER AND POLYAMIDE WHICH COMPRISES INCORPORATING IN THE POLYMER BLEND, PRIOR TO EXTRUSION THEREOF, ABOUT 0.05 TO 3 WEIGHT PERCENT, BASED UPON THE WEIGHT OF THE POLYAMIDE AND POLYESTER, OF AN ORGANIC PHOSPHORUS COMPOUND AND ABOUT 0.05 TO 3 WEIGHT PERCENT, BASED UPON THE WEIGHT OF THE POLYAMIDE AND POLYESTER, OF A STERICALLY HINDERED PHENOLIC COMPOUND AND MELT EXTRUDING THE POLYMER BLEND TO FORM A FILAMENT HAVING INCREASED WHITNESS.read more

Helmut Muller,Kurt Schwarzenbach +1 more
TL;DR: The use of symmetrical triarylphosphites of the general formula I ##STR1## wherein R1 is tert.-butyl, 1,1-dimethylpropyl, cyclohexyl or phenyl, and one of R2 and R3 is hydrogen and the other is hydrogen, methyl, tert.- butyl, one, 1-dimethyltimethylpolytope (THP), cyclo-hexyl and phenyl was proposed in this paper.

Stabilization systems from triarylphosphites and phenols
TL;DR: In this paper, a triarylphosphite of the general formula "STR1" was used for stabilizing polyolefins, where R 1 represents tert-butyl, 1,1-dimethylpropyl, cyclohexyl or phenyl, and one of R 2 and R 3 is hydrogen and the other is hydrogen, methyl, tert.-butyl and a phenolic antioxidant.
Patent
A process for preparing graft and block copolymers
TL;DR: In this article, a process for preparing block, and/or graft copolymeric compositions by forming an intimate mixture of two or more polymers, at least one of which includes one or more amino junctions and at least two remaining polymers including carboxylic acid junctions, and an effective amount of a phosphite compound, is described.
Patent
Polyester compositions having improved wear characteristics
TL;DR: In this article, the authors proposed a migrator package to push a disproportionate amount of the fluorinated polyolefin within the subsurface of a thermoplastic molding composition to augment the wear resistant effect.
Patent
Stabilized (poly)ester/(poly)carbonate blend
TL;DR: Compositions comprising a diester or polyester, e.g., 1,4-butylene dibenzoate or poly(1,4)-butylene terephthalate, in combination with an organic carbonate OR polycarbonate, are stabilized with boric acid as mentioned in this paper.
