Method for the manufacture of a colored polymer composition comprising a polymer, a release agent and a colorant, the method comprising the steps of feeding a solid form of a release agent composition comprising said release agent and said colorant to a feed section of a melt mixing device, feeding said polymer to said melt mixing device and mixing said release agent composition and said polymer in said melt mixing device at a temperature above the melting temperature of said polymer, wherein—said colorant is a pigment, or a dye which is soluble in said release agent, —said polymer comprises or consists of polycarbonate, —the release agent is selected from the group consisting of penta-erythritol tetra stearate, glycerol monostearate, glycerol tristearate and mixtures thereof.

Method for the manufacture of a colored polymer composition

A foamable poly carbonate composition comprising 5 to 95 wt % of a poly(siloxane) block copolymer comprising a poly(carbonate-siloxane) comprising 50 to 99 wt % of bisphenol A carbonate units and 1 to 50 wt % of dimethylsiloxane units, each based on the weight of the poly(carbonate-siloxane), a poly(ester-carbonate-siloxane) comprising bisphenol A carbonate units, isophthalate-terephthalate-bisphenol A ester units, and 5 to 200 dimethyl siloxane units, or a combination thereof; 5 to 95 wt % of an auxiliary component comprising a poly(alkylene ester), a poly(ester-carbonate), or a combination thereof, and optionally, a homopolycarbonate; optionally, up to 10 wt % of an additive composition, wherein the composition has a glass transition temperature of 140° C. and below measured using differential scanning calorimetry, and wherein a foamed sample of the composition has an average cell size of 10 nanometers to 20 micrometers.

Low temperature foamable polycarbonate composition and articles thereof

Provided are extrusion dies having entrance, orientation, merging (), and exit () sections, which dies may be used to produce fibers having, e.g., oriented reinforcement materials (e.g., PTFE) dispersed within. The dies provide fibers having enhanced mechanical and processing properties. The orientation section comprises orientation channels () wherein a ratio of a cross-sectional area having of the channel inlet to a cross-sectional area of the channel outlet is between 2 and 45.

Die design for property enhancement

In one embodiment, a multilayer article can comprise: a multilayer substrate M, comprising: greater than or equal to 16 polymer A layers, preferably 16 to 512 polymer A layers; and greater than or equal to 16 polymer B layers, preferably 16 to 512 polymer B layers; wherein the polymer A layers and the polymer B layers are present in a ratio of 1:4 to 4:1, preferably the ratio is 1:1; a protective layer P; and an identification layer I between the protective layer P and the multilayer substrate M; wherein the identification layer I comprises information, and wherein the protective layer P prevents alteration thereof.

Multilayer identity article and methods of making the same

A multilayer film can comprise: a plurality of layers, preferably 4 layers to 128 layers, comprising: a polymer A layer comprising a polycarbonate copolymer and a polymer B layer comprising a semi-crystalline polyester; wherein a differential solubility parameter (&#x394;&#x3b4;) of polymer A towards polymer B (&#x394;&#x3b4;) is greater than or equal to 2.6 MPa; and an interdiffusion region between each polymer A and polymer B. The multilayer film has a dynamic flexure of greater than or equal to 200,000 cycles, as determine by bending 180&#xb0; on a 10 mm radius cylinder at a rate of 1 hertz. The multilayer film has a total thickness of 40 &#x3bc;m to 70 &#x3bc;m, a transmission at 360 nm to 750 nm of greater than or equal to 89% and a haze of less than or equal to 1%.
