Abstract: A process for preparing a composite material is disclosed wherein the process comprises: A) sizing a natural fiber with a reactive organosilane; B) mixing the sized natural fiber with a polyolefin resin; and C) adding a functionalized polyolefin coupling agent to the mixture of the sized natural fiber and the polyolefin resin to provide said composite material.

Abstract: The present invention is directed to a composition comprising a white pigment or extended white pigment surface treated with a silane having at least one functional group capable of reacting with acids and anhydrides, at least one polymeric material and a compatibilizer. Once treated, the pigment has improved processability and dispersibility in polymeric materials. Silanizing the pigment also enhances the brightness (increase whiteness and reduce yellowness) of the pigment.

Abstract: The present invention relates to the silanization or surface treatment of minerals with alkylsilanes and alkylsilane copolymers. More specifically, the present invention relates to alkylsilane copolymers useful for surface treating pigments or fillers. The alkylsilane copolymers comprise at least two different monomers. The copolymers find particular utility for the surface treatment of white pigments, such as titanium dioxide, for improving the dispersibility and processibility of the pigments when compounded with a polymeric material, in particular, when compounded with polyolefins.

Abstract: The specification discloses a polymer blend especially well-suited for coating paperboard substrates used in food packaging, particularly acidic or acid-generating foods such as fruit and vegetable juices. The blend contains an acid-activatable oxygen scavenger dispersed in a film-forming synthetic polymer such as an EVOH copolymer. When placed as a film or layer on the side of the substrate inside the container in contact with the food the blend is effective to reduce the oxygen in the container over time to a very low concentration, replacing the same with carbon dioxide, for an excellent preservative effect.
