Patent number: 6469072Abstract: A method for dispersing solid forms of additives in polymers involves adding dispersions or solutions of additive(s) to a solution of polymer in a tubular mixer (preferably in the presence of a stationary mixer).

Patent number: 6017993Abstract: A resin composition comprising a thermoplastic resin and a titanium dioxide (TiO.sub.2) pigment and having a moisture content of 10-1,400 ppm as determined by a specific method. A preferable resin composition is made by (i) atomizing 0.1-3.0 wt. parts of an organopolysiloxane within a fluidized powder layer of 100 wt. parts of TiO.sub.2 pigment; (ii) mixing 1-5 wt. parts of a metallic soap with 100 wt. parts of the TiO.sub.2 pigment; (iii) heat-treating the thus-obtained mixture at 70-200.degree. C. for 10 min-2 hours; and then (iv) mixing a thermoplastic resin with the heat-treated mixture. The resin composition is used for coating paper or film, when it contains 20-60 wt. % of TiO.sub.2 pigment. The resin composition is used as a master batch for the preparation of a resin composition for coating paper or film, when it contains 30-80 wt. % of TiO.sub.2 pigment.Type: GrantFiled: August 8, 1997Date of Patent: January 25, 2000Assignee: Showa Denko Kabushiki KaishaInventors: Masashi Maeda, Katsura Ito

Patent number: 6005025Abstract: A method for dispersing solid forms of additives in polymers involves adding dispersions or solutions of additive(s) to a solution of polymer in a tubular mixer (preferably in the presence of a stationary mixer). The mixer leads to a steam precipitation step wherein all fluid ingredients in the mixture are volatilized leaving the solid additive and resin in the desired ratio. This results in a uniform dispersion of the additives in the polymer matrix. As a result of the high dispersion, physical properties of a thermoplastic resin, to which the polymer matrix has been added are preserved. In one illustration, PTFE as a drip inhibitor additive, is added to polycarbonate to obtain a highly dispersed PTFE concentrate of improved drip-inhibition without loss of mechanical properties when added to a thermoplastic molding resin.Type: GrantFiled: January 5, 1998Date of Patent: December 21, 1999Assignee: General Electric CompanyInventors: Qamar S. Bhatia, Paul Buckley, Gary Davis, Robert L. Howe, Wie-Hin Pan, Elliott Shanklin

Patent number: 5998528Abstract: Intercalates formed by contacting the layer material, e.g., a phyllosilicate, with an intercalant to sorb or intercalate the between adjacent platelets of the layered material. Sufficient intercalant polymer is sorbed between adjacent platelets to expand the adjacent platelets at least about 5 .ANG. (as measured after water removal to 5% by weight water), up to about 100 .ANG. and preferably in the range of about 10-45 .ANG., so that the intercalate easily can be exfoliated into individual platelets. A monovalent, divalent and/or trivalent cation is added to the intercalating composition, or after intercalation for surprising increases in viscosity. The intercalated complex is combined with an organic liquid into an unexpectedly viscous carrier material, for delivery of the carrier material, or for delivery of an active compound, e.g., a pharmaceutical, or cosmetic, or lubricant, e.g., food grade lubricants dissolved or dispersed in the carrier material.Type: GrantFiled: February 2, 1998Date of Patent: December 7, 1999Assignee: Amcol International CorporationInventors: Semeon Tsipursky, Vladimir Dolinko, Vasiliki Psihogios, Gary W.

Patent number: 5990202Abstract: Ink-jet inks for ink-jet printing are provided which include a vehicle and a colorant, the colorant encapsulated by or associated with a primer core/shell polymer to form a primer/colorant combination, and the primer/colorant combination, upon printing on a print medium, encapsulated by a durable core/shell polymer. The primer core/shell polymer serves to provide adhesion of the durable core/shell polymer to the colorant and the durable core/shell polymer serves to provide a smear-fast film upon drying of the ink on a print medium. The primer core/shell polymer comprises a hydrophobic core and a hydrophilic shell comprising a polar component, while the durable core/shell polymer comprises a hydrophobic core comprising a low T.sub.g component, which, when homopolymerized, has a glass transition temperature, T.sub.g, below 25.degree. C. and a high T.sub.g component, which, when homopolymerized, has a glass transition temperature above 25.degree. C.Type: GrantFiled: December 24, 1997Date of Patent: November 23, 1999Assignee: Hewlett-Packard CompanyInventors: Khe C Nguyen, Sivapackia Ganapathiappan
