Disclosed is a process for making nitrated styrenic fluoropolymers having various degrees of substitution. The nitrated styrenic fluoropolymer is capable of providing an exceptionally high birefringence ranging from 0.02 to 0.036. Further, the birefringence can be tuned by varying the degree of substitution (DS) of the nitro group on the styrenic ring to meet the need for optical compensation film applications. More particularly, the optical compensation films of the present invention are for use in an in-plane switching LCD (IPS-LCD) and OLED display.

Method for the preparation of nitrated styrenic fluoropolymers

Disclosed is a multilayer optical compensation film comprising a first layer comprising a positive C-plate material and a second layer comprising a polyimide, as well as polymer compositions and resins and solutions containing said polymer compositions. The optical compensation film has a reversed wavelength dispersion that is capable of providing an achromatic (or broadband) retardation compensation. The optical film can be used in optical devices such as liquid crystal displays (LCD) or organic light emitting diode (OLED) displays.

Multilayer optical compensation film having reversed wavelength dispersion

Disclosed is an optical compensation film made of a solution cast of a polymer blend comprising a nitrated styrenic fluoropolymer and a polyimide. The compensation film is a positive-C plate having reversed wavelength dispersion that is capable of providing an achromatic (or broadband) retardation compensation. The optical film of the invention can be used in an optical device such as liquid crystal display (LCD) or organic light emitting diode (OLED) display.

Extrusion blow molded (EBM) articles comprising a polyester having a dicarboxylic acid component and a glycol component. The dicarboxylic acid component comprises at least 90 mole % terephthalic acid residues. The glycol component comprises at least 75 mole % ethylene glycol residues and 15 to 25 mole % residues of a difunctional glycol such as, for example, 1,4-cyclohexanedimethanol. Such EBM articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.

Extrusion profile articles comprising a polyester having a dicarboxylic acid component and a glycol component. The dicarboxlyic acid component comprises at least 90 mole % terephthalic acid residues. The glycol component comprises at least 75 mole % ethylene glycol residues and 15 to 25 mole % residues of a difunctional glycol such as, for example, 1,4-cyclohexanedimethanol. Such extrusion profile articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.

Extrusion profile articles

The invention is generally directed to baby bottles and other articles produced by blow molding from polymeric materials having glass transition temperatures ranging from 100&#xb0; C. to 130&#xb0; C., as well as to processes for producing them. These articles can be exposed to boiling water and can be produced by using a suitable combination of a stretch ratio of less than 3 and a preform temperature at least 20&#xb0; C. greater than the glass transition temperature (Tg) of the polymeric material.
