    Abstract: The invention relates to a novel nanocomposite having improved processing characteristics. The nanocomposite comprises polyolefins and a nanofiller, selected from one or more of the group consisting of oxides of Si, Ti, Zr, Sn and Al. The dynamic viscosity of the nanocomposite including the nanofiller is lower than the dynamic viscosity of the nanocomposite without nanofiller.

    Abstract: The present invention relates to a PVC based nanocomposite resin composition with superior impact strength and a method for preparing the same. The method according to the present invention comprises the steps of: adding nano calcium carbonate and a lipophilic dispersing agent to a vinyl chloride monomer; adding the resultant mixture system to an aqueous solution system comprising deionized water, a suspension stabilizer and apolymerization initiator to prepare a suspension system and performing polymerization at an elevated temperature to prepare a PVC based nanocomposite resin composition; and processing the PVC based nanocomposite resin composition with at least one impact modifier selected from the group consisting of a methyl methacrylate-butadiene-styrene copolymer, an acrylic impact modifier and a chlorinated polyethylene. Preferably, the nano calcium carbonate is uniformly distributed in the vinyl chloride particles, so that improvement in impact strength and reduction of impact modifier required for processing the resin can be attained.

    Abstract: The invention relates to polymer-nanocomposite blends comprising at least two polymers and layered silicates which are delaminated in a nanodispersed manner and have advantageous properties. Also disclosed are methods for the production thereof. The inventive polymer-nanocomposite blends contain: a) 55 to 95 percent by weight of polyamide (PA); b) 4 to 40 percent by weight of polypropylene (PP); c) 1 to 9 percent by weight of nanodispersed layered silicates; and d) up to 10 percent by weight of carboxylated polyolefins, particularly ethylene copolymers comprising unsaturated carbonic acids, such that the percentage by weight of the respective compositions is always 100 percent. Optionally, common stabilizers and fillers can be added. The inventive nanocomposite blends are characterized by great stiffness in the freshly injected and conditioned state, reduced water absorption, improved thermooxidative stability, and no reduction of toughness.
