摘要： In an improved polymer melt cutter a gas is added to the cooling liquid before the cooling liquid enters the cutting chamber, or is added directly through the cutting chamber wall. This forms a cooling liquid/gas mixture in the cutting chamber, which has the advantage of providing easier startups, lower operating costs, and other advantages. Processes associated with the improved polymer melt cutter are also disclosed.

摘要： Spherical-shaped particles having an average diameter of 10 to 100 microns and the surface thereof is covered with hemispherical-shaped bumps about 0.1 micron in diameter, the particles being a copolymer of alpha-olefins and alpha, beta-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms, the copolymer having up to 90% of the carboxylic acid groups ionized by neutralization with metal ions. The particles form a free-flowing powder useful in preparing clear, protective, shatter-resistant coatings for glass, and protective coatings for metals and other material.

摘要： Underwater melt pelletizer dies which have a highly thermally conductive pathway from their heating source to the vicinity of the polymer exit end of their die holes and have a thermally insulating material at that end of their die holes have improved operability and can pelletize thermoplastics which are otherwise difficult or impossible to pelletize with such an apparatus.

摘要： A polymer cutter with a rotary cutting head in which the cutting edges are on the circumferential periphery of the head, and in which the cutting edges shear rather than slice the polymer is described. The knife blades on the rotary head have a cutting edge angle of greater than 70°. The apparatus is especially useful for cutting thermoplastics and may be used for preparing polymer granules or pellets.

摘要： Disclosed herein are thermotropic liquid crystalline poly(ester-amides) containing repeat units derived from alipatic diamines and other monomers, such as aromatic diols, aromatic dicarboxylic acids, aromatic hydroxycarboxylic acids, and optionally aliphatic diols. The polymers are particularly useful as films and in multilayer structures as barrier layers because of their relatively low permeability to various compounds.

摘要： A liquid crystal polymer composition comprising specified amounts of unsized glass filler and a liquid crystalline polymer having a melting point of about 280° C. or more has improved high temperature stability compared with similar compositions containing sized glass fillers. The compositions are particularly useful where the composition is exposed for long time periods to high temperatures, such as parts in electrical and electronic apparatus, and cookware.
