6414083, Jul 2, 2002

Filed:

Sep 11, 2001

Appl. No.:

09/951227

Inventors:

Sebastian Plamthottam - Upland CA

Assignee:

Tactyl Technologies, Inc. - Vista CA

International Classification:

C08J 303

US Classification:

525 98, 524505, 524484, 524487, 524556, 524576

Abstract:

A dispersion has particles dispersed in a continuous aqueous dispersion medium. The particles, preferably no more than about 2 micrometers in size, are formed of a mixture of styrene-ethylene/butylene-styrene (S-EB-S) block copolymer having end blocks each with a weight average molecular weight of more than about 15,000 Daltons and an oil such as a mineral oil. The dispersion medium is a mixture of water and a surfactant. Articles are prepared by dipping a form into the dispersion and withdrawing the form to leave a film of the dispersion on the form. The water is evaporated from the film, leaving a coherent extensible film on the form.

Tactyl Technologies, Inc. - Vista CA

International Classification:

C08L 900

US Classification:

524571, 524575, 21617, 264301, 264303, 604349

Abstract:

An elastomeric composition includes a single S-EB-S block copolymer having at least about 15 weight percent of styrene end blocks, wherein the weight average molecular weight of the styrene end blocks is at least about 7,000 Daltons and the weight average molecular weight of ethylene-butylene midblocks is at least about 60,000 Daltons, and a plasticizer in an amount sufficient to provide tactility in products made from the composition. To prepare articles such as medical film protective devices, the elastomeric composition is dissolved in a sufficient amount of a solvent to permit dip forming. A form having the shape of the desired product is dipped into the solution to build up a film of the elastomeric composition on the form. The dip-formed elastomeric films are free of pinholes and resistant to oxidative and ozone attack. The films are particularly suitable for use in products such as examination, surgical, and industrial gloves and condoms.

Abstract:

A method for the extraction, separation, fractionation and purification of biopolymers from plant materials using supercritical and/or subcritical solvent extractions is disclosed. Specifically, the process can be used for the separation of resins and rubber from guayule shrub (), and other rubber and/or resin containing plant materials, using supercritical solvent extraction, for example supercritical carbon dioxide extraction. Additionally, polar and/or non-polar co-solvents can be used with supercritical carbon dioxide to enhance the selective extraction of resins and rubbers from the shrub.

Avery Dennison Corporation - Pasadena CA

International Classification:

C08F26504
C08F26706

US Classification:

525278

Abstract:

There are synthesized certain polycylic-vinyl reactive tackifiers for acrylic based pressure-sensitive adhesive polymers. The compounds have reactive pendant vinyl groups which copolymerize and graft to the adhesive polymer by means of UV or EB radiation. There are also provided novel pressure-sensitive adhesive compositions containing such reactive tackifiers.
