Patent number: 5866222Abstract: There is provided a block, segmented or graft copolymer having polyorganosiloxane segments and self-associating hard segments, which copolymer is capable of forming a solid, generally non-tacky release coating without the requirement of curing. The release coating comprises the polyorganosiloxane copolymer admixed with an MQ resin wherein the amount of MQ resin is generally between 1 and 30 weight percent of the polyorganosiloxane content preferably 1 to 20 weight percent. The MQ resin modifies the copolymer release material to have a higher release than the copolymer itself, generally at least 10 percent and preferable at least 20 percent up to 50 percent or higher with the readhesion values decreasing by 50 percent or less, preferably 40 percent or less.Type: GrantFiled: July 18, 1997Date of Patent: February 2, 1999Assignee: Minnesota Mining and Manufacturing Co.Inventors: Jayshree Seth, Stephen W. Bany, David J. Kinning

Patent number: 5719219Abstract: There is provided a melt extrudable, moisture curable thermoplastic polymer which is produced from a silane modified elastomeric polymer and which has improved hysteresis, reduced stress decay and improved creep properties. The polymer may be processed into a nonwoven web, film or foam which may be laminated to other materials such as spunbond polyolefin layers and may be used in medical, personal care, feminine hygiene and other applications.Type: GrantFiled: May 25, 1996Date of Patent: February 17, 1998Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Ketan N. Shah, Stephen M. Campbell
