Needle comprising a polyarylene material comprising a polyarylene. The needle can meet all the advantages of metal, while avoiding its drawbacks. It has a high rigidity and ductility, and is excellent in penetrability and ability to hold a sharp edge. It is easily disposable and recyclable. It is non toxic and non irritant.

Needles made of a particular plastic material

Blend (B) comprising at least one polyarylene in a form other than fibers, and at least one poly(aryl ether ketone). Blend (T) comprising at least one polyarylene, at least one poly(aryl ether ketone) and at least one poly(aryl ether sulfone). Article or part of an article comprising the blend (B) or the blend (T).

Polyarylene composition

A composition, having an improved resistance to yellowing under heat aging, comprising at least 20 weight % of at least one polycondensation polymer having a heat deflection temperature of above 80&#xb0; C. under a load of 1.82 MPa when measured according to ASTM D648, from 0 to 5 weight % of at least one polymer having a heat deflection temperature of at most 80&#xb0; C. under a load of 1.82 MPa when measured according to ASTM D648, a white pigment; and a black pigment provides resistance to heat aging induced yellowing. The polycondensation polymers are advantageously selected from the group consisting of polyarylethersulfones, at least partially aromatic polyamides, polyamideimides, liquid crystalline polymers, polyimides, polyetherimides, polyaryletherketones, and polyphenylene sulfides. The polymer composition can be molded to form a variety of articles, including LED components, such as reflectors, reflector cups, and scramblers.

Anti-yellowing polycondensation polymer compositions and articles

Process for the preparation of latices by batchwise radical polymerization of one or more monomers, comprising the participation, in the polymerization, of: (a) one or more fine dispersions of one or more finely dispersed monomers and (b) one or more seed latices of one or more seeding polymers.
