US Classification:

524445, 524446, 524447, 501145, 501146, 501148

Abstract:

Intercalated layered materials prepared by co-intercalation of a multi-charged onium ion spacing/coupling agent and a matrix polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The spacing of adjacent layers of the layered materials is expanded at least about 3 , preferably at least about 5 , usually to about 15-20 , e. g. , 18 with the di-charged onium ion spacing/coupling agent. The intercalation of the matrix polymer then increases the spacing between adjacent layers to at least about 15 , preferably to about 20 to about 30.

US Classification:

524445, 524446, 524186

Abstract:

Nylon-intercalated (concentrate nylon), layered silicates, in concentrated form, containing at least 6% to about 40% by weight layered silicate, preferably about 8% to about 30% by weight layered silicate, intercalated with a nylon that is polymerized while in contact with the clay, during ring-opening polymerization of the nylon reactants (monomers) and melt processing. The in-situ nylon polymerization reaction to form the concentrate nylon is continued until the number average molecular weight (Mn) of the nylon is about 25,000 or less, preferably 15,000 or less, more preferably about 5,000-10,000, to maintain melt processability of the resulting concentrate.

International Classification:

C08J 5/10
C08K 3/34

US Classification:

524445, 524186, 501145, 501147

Abstract:

A resin composition comprising melt blending a polyamide resin such as nylon MXD6 with a polyphenoxy resin. The polyamide resin and the polyphenoxy resin may be combined prior to or after melting and can be sandwiched between two PET layers in a perform mold to form an article capable of blow molding to form a container with improved delamination resistance. Also, intercalated layered materials are prepared by co-intercalation of an onium ion, an aromatic polyamide oligomer or polymer, e. g. , nylon MXD6, and a polyphenoxy oligomer or polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The co-intercalated layered materials are combined with the aromatic polyamide and polyphenoxy resin to form a nanocomposite composition for sandwiching between PET layers to form containers having improved delamination resistance.

International Classification:

C08L 77/00

US Classification:

523216, 252378 R, 524445, 524606

Abstract:

Intercalates, exfoliates thereof, and nanocomposite compositions are formed by intercalating a layered silicate material, e. g. , a phyllosilicate, with an oligomer or polymer intercalant that is a reaction product of at least one diamine with at least one dicarboxylic acid, to form a polyamide oligomer containing a xylylenediamine component. The oligomer or polymer may be formed in-situ by contacting the layered phyllosilicate with polymerizable monomer reactants using conditions to cause reaction and polymerization in the intercalating composition and intercalation of the resulting oligomer and/or polymer, between platelet layers of the phyllosilicate. An amine functionality of the oligomer or polymer is protonated for ion-exchange with interlayer cations of the phyllosilicate to bond the intercalant to the phyllosilicate platelet, at the protonated amine, at a negative charge site previously occupied by the interlayer cations.

Abstract:

Intercalated layered materials prepared by co-intercalation of a multi-charged onium ion spacing/coupling agent and a matrix polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The spacing of adjacent layers of the layered materials is expanded at least about 3. ANG. , preferably at least about 5. ANG. , usually to about 15-20. ANG. , e. g. , 18. ANG. with the di-charged onium ion spacing/coupling agent. The intercalation of the matrix polymer then increases the spacing between adjacent layers to at least about 15. ANG. , preferably to about 20. ANG. to about 30. ANG.

International Classification:

B01D 2101

US Classification:

516101

Abstract:

Intercalates formed by contacting a layered material, e. g. , a phyllosilicate, with an intercalant surface modifier selected from the group consisting of a compound having an alkyl radical containing at least 6 carbon atoms, a compound containing an aromatic ring, and mixtures thereof, said surface modifier including a matrix material-reactive functional group, to sorb or intercalate the intercalant surface modifier between adjacent platelets of the layered material. Sufficient intercalant surface modifier is sorbed between adjacent platelets to expand the adjacent platelets to at least about 10. ANG. , up to about 100. ANG. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix.
