Abstract: Flexible polyurethane foams are prepared by reacting a polyisocyanate with a high equivalent weight polyol. At least a portion of the high equivalent weight polyol is a polyester containing hydroxymethyl groups. The high equivalent weight polyol further includes species containing tertiary amine groups. The presence of tertiary amine-containing polyols in the formulation leads to improvements in resiliency, tensile and/or tear strength.

Abstract: A reactive extrusion process for producing an ionomer is disclosed. The process comprising adding a polymer containing a carboxyl functionality to an extruder, then homogenously melting the polymer in a melting zone of the extruder. A first melt seal zone of the extruder is formed to separate the melting zone from an injection zone where an aqueous solution of metallic ions are added to the molten polymer. The first melt seal zone is formed by increasing the pressure in the melt seal zone to a pressure which is higher than the vapor pressure of the water at any point in the injection zone and the reaction zone. The aqueous solution of metallic ions is then mixed with the polymer containing the carboxyl functionality in a reaction zone of the extruder under conditions such that the metallic ions are substantially reacted with the carboxyl functionality.

Abstract: Blend compositions containing a novel homopolymer, the use of which allows the incorporation of more comonomer in the additional components of the blend (for the same overall density) resulting in increased tie molecule formation and improvement in properties such as ESCR, toughness and impact strength are disclosed. The homopolymers are important for applications where a high density is needed to ensure certain mechanical properties like abrasion resistance, indentation resistance, pressure resistance, topload resistance, modulus of elasticity, or morphology (for the chlorination of PE to CPE) and additional advantages such as melt processability. The blend can be obtained by dry or melt mixing the already produced components, or through in-situ production by in parallel and/or in series arranged reactors. These resins can be used in applications such as films, blow molded, injection molded, and rotomolded articles, fibers, and cable and wire coatings and jacketings and, various forms of pipe.
