A polyolefin-based nanocomposite and a method of preparing the same are disclosed. The polyolefin-based nanocomposite is prepared by melt kneading a mixture including (A) 40-99.8% by weight of a matrix polymer of polyolefin; (B) 0.1-30% by weight of a polyolefin compatilizer containing polar reactive groups; and (C) 0.1-30% by weight of a layered clay material having a quaternary ammonium ion bonded to the surface thereof. The quaternary ammonium ion contains (I) at least one alkyl group having at least 15 carbon atoms; and (ii) a substitutent having &#x2014;Si&#x2014;O&#x2014;Si&#x2014;linkage and at least one terminal reactive group.

Polyolefin-based nanocomposite and preparation thereof

The present invention relates to a polymer nanocomposite and the process for preparation of the same, wherein a positive-electric polyelectrolyte, a layer-structured inorganic material, such as silicate clay, and a polymer latex comprising an negative-electric surface are &ldquo;co-agglutinated&rdquo; to result in a polymer nanocomposite.

Polymer nanocomposites and the process of preparing the same

A method for the polymerization of Nylon 6 from caprolactam and water using a catalyst composition comprising a primary catalyst, which can be an alkali metal hypophosphite or an alkali-earth metal hypophosphite, and an amine cocatalyst. The amine cocatalyst can be selected from the group consisting of phenylene diamines, hindered amines, poly(hindered amines), Group I benzotriazoles, and Group II benzotriazoles. The catalyst composition used in this invention is most useful when used in conjunction with the reactive extrusion technology which requires a very fast polymerization rate to take full advantage of this evolving technology.
