Patent number: 7316842Abstract: High-viscosity elastomeric adhesive compositions including a high softening point tackifier resin in combination with a base polymer can be used to create elastomeric composite laminates having effective adhesion and elastic properties. The elastomeric adhesive compositions suitably have a viscosity between about 100,000 and about 500,000 cps at between about 300 degrees Fahrenheit (149 degrees Celsius) and about 350 degrees Fahrenheit (177 degrees Celsius). Facing layers, such as nonwoven webs, films, elastic strands, fastening material, absorbent material, and the like, can be laminated to one or both surfaces of the elastomeric compositions to form elastomeric composite laminates. A method of making such compositions and laminates involves forming the compositions into elastomeric adhesive films and/or strands.Type: GrantFiled: November 4, 2003Date of Patent: January 8, 2008Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Peiguang Zhou, Gregory K.

Patent number: 7186776Abstract: The present invention relates to a sulfur-cross-linkable elastomeric composition that is useful for the manufacture of tires. This elastomeric composition is based on at least one isoprene elastomer (in particular natural rubber), a reinforcing inorganic filler (in particular, silica), and an (inorganic filler/isoprene elastomer) coupling agent. The coupling agent is a multifunctional polyorganosiloxane (POS), which comprises functions denoted as “Y” and “X”, wherein the Y function is at least one hydroxyl or hydrolyzable function grafted to the silicon atoms of the coupling agent and the X function is a group bearing at least one activated ethylene double bond and is grafted to the silicon atoms of the coupling agent. This POS is, in particular, a POS having an imide, acid or ester function, the ethylene double bond of which is activated by at least one adjacent carbonyl group (—C?O).Type: GrantFiled: September 22, 2004Date of Patent: March 6, 2007Assignee: Michelin Recherche et Technique S.A.Inventors: Jean-Claude Tardivat, Salvatore Pagano, Christel Thonier, Nathalie Guennouni
