Polymers are disclosed that incorporate portions of secondary or tertiary polyamide segments connected with polyisocyanates. These polymers have enhanced matting properties. The enhanced matting properties are from creating an inherently matt surface from the polymer without the use of any separate fine particle size matting additives. Conventional matting agents such as fine particle size silica usually results in loss of physical properties such as haze development and porosity in the coating from the matting agent. Composites and hybrids of these polymers and other polyamides, polyurethane with vinyl polymers (acrylates) are also disclosed and claimed.

A core/shell polymer material suitable for three-dimensional printing is provided. The core/shell polymer material may include at least one amorphous polymer as a core particle and at least one semicrystalline polymer as a shell material surrounding the core particle.

Components for articles of footwear and athletic equipment including a foam are provided. The foam portion of the components and articles include a composition which includes a thermoplastic copolyester, the composition having a foam structure. A polymer layer is provided on at least on surface of the foam portion. The polymer layer can control or reduce the water uptake of the foam portion. Methods of making the compositions, foams, and components are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding, or injection molding followed by compression molding.

A thermoplastic composition includes: a thermoplastic polymer including from about 30 wt % to about 90 wt % poly(methyl methacrylate) (PMMA) and from about 5 wt % to about 70 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 20 wt % to about 60 wt %; and a plurality of photoluminescent materials including quantum dots.

A method for producing a modifier for preparing a composite material based on a thermoplastic polymer where the thermoplastic polymer is mixed with a solvent and salts of alkali metals with the following ratio of components (wt. %): thermoplastic polymer—3-15, solvent—70-94, salts of alkali metals—3-15, until the polymer is fully dissolved, and then carbon nanotubes are added to the mixture in an amount up to 5 wt. % while stirring to produce a dispersion, then a coagulant is added to the dispersion under continuous stirring, the resulting dispersion is then filtered, and the filter cake is rinsed and dried up. The solvent is selected from the group of: alcohol, or N-methylpyrrolidone, or dimethylacetamide. The alkali metal salt is lithium chloride or calcium chloride. The carbon nanotubes are single-wall carbon nanotubes.
