Abstract: One method for making a laminate material comprising a first surface layer comprising resorcinol arylate polyester chain members and a second surface layer suitable for bonding to a substrate, comprises co-extruding a polymeric first surface layer material and a polymeric second surface layer material through a die and into the first nip of a calender roll stack comprising a first surface roll and a second surface roll that define the first nip, to form the laminate material. A nip load in the first nip of greater than or equal to about 400 N/cm can be applied to the laminate, and the laminate material can be collected from the roll stack. The first roll and the second roll can each have a surface smoothness of less than or equal to about 5 micrometers and temperatures of about 40° C. to about 150° C.

Abstract: Disclosed is a formable thermoplastic multi-layer laminate comprising an outer layer comprising a polymer comprising resorcinol arylate polyester chain members, a middle layer comprising a thermoplastic polymer, an inner-tie layer comprising a thermoplastic polymer comprising a carbonate polymer and an acrylonitrile-styrene graft copolymer comprising at least one of an acrylonitrile-styrene-acrylate graft copolymer (ASA) or an acrylonitrile-butadiene-styrene graft copolymer (ABS), the middle layer being between the outer layer and the inner-tie layer and being in contact with both the outer layer and the inner-tie layer. Also disclosed are a formed multi-layer laminate and an article comprising the multi-layer laminate bonded to a substrate. A method of making the article is also disclosed.

Abstract: The stability of an azadirachtin-containing solid preparation is increased if the preparation contains about 5% or less volatile polar solvents and 1% or less water. Reduction of the percentage of volatile polar solvents present in preparations of azadirachtin-containing solids to such levels improves the storage-stability of the solids without significantly degrading the azadirachtin in the solid. Solvents are preferably removed by drying the preparation at a suitable temperature for a time sufficient to reduce the level of water and volatile polar solvents to acceptable levels.

Abstract: Disclosed is an improved method of extracting neem seeds. The method involves co-solvent extracting neem seeds with a solvent mixture of a nonpolar, aliphatic hydrocarbon solvent and a polar solvent to simultaneously remove the hydrophilic and hydrophobic extracts from the neem seeds. The method provides novel neem extract mixtures which contain both the hydrophobic and hydrophilic portion of the neem seeds. The extract mixtures may be further extracted to yield an azadirachtin-containing solid product having greater than 10 weight percent of azadirachtin.
