In an embodiment, a composition comprises a polycarbonate; 1 to 5 wt % based on a total weight of the composition of a nanosilica having a Dparticle size by volume of 5 to 50 nanometers; wherein the nanosilica has a hydrophobic coating; and a siloxane domain having repeat units of the formula 10; wherein each R is independently a Cmonovalent organic group and the value of E is 2 to 1,000; wherein the composition comprises at least one of a polycarbonate-polysiloxane copolymer, 0.1 to 5 wt % of a polysiloxane homopolymer based on the total weight of the composition, or a plurality of polysiloxane particles having a Dparticle size by volume of 0.1 to 10 micrometers.

Impact compositions

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

Provided are thermoplastic-nanoparticle compositions that exhibit enhanced powder and melt flow. The disclosed compositions, comprising nanoparticles being silylated, have particular application in additive manufacturing processes, such as selective laser sintering and other processes.
