Patent number: 7067585Abstract: A hot melt adhesive composition is based on an isotactic polypropylene random copolymer (RCP). The composition contains about 4%–50% by weight of the RCP copolymer, about 20%–65% by weight of a compatible tackifier, about 0%–40% by weight of a plasticizer, about 0%–3% by weight of a stabilizer, about 0%–40% by weight of a wax, and optionally about 0%–60% by weight of an atactic poly-?-olefin (APAO). The adhesive composition may be used in a number of applications such as, for example, in disposable nonwoven hygienic articles, paper converting, flexible packaging, wood working, carton and case sealing, labeling and other assembly applications.Type: GrantFiled: October 28, 2002Date of Patent: June 27, 2006Assignee: Bostik, Inc.Inventors: Baoyu Wang, Monina Dadap Kanderski, Lacretia A.

Patent number: 6984696Abstract: Compositions are provided having from 70 wt % to 95 wt % of a polymer selected from homopolymers and random copolymers of propylene and from 5 wt % to 30 wt % of a miscible hydrocarbon resin with a glass transition temperature greater than 20° C. The polymer has a heat of fusion of less than 50 J/g, a melt index (MI) of less than 20 dg/min, and contains stereoregular propylene crystallinity. Also provided are films containing such compositions, and articles, such as diapers or incontinence garments, including such films.Type: GrantFiled: March 28, 2003Date of Patent: January 10, 2006Assignee: ExxonMobil Chemical Patents Inc.Inventors: Christopher L. Curry, Sudhin Datta -
Patent number: 6953541Abstract: The present invention provides a method for preparing flexible thermoplastic compositions that may be used separately or combined with up to fifty percent thermoplastic scrap. One embodiment of the invention comprises creating a melt-blend of blending composition, up to 50% by weight thermoplastic scrap and up to 15% by weight poly(ethyl-co-vinyl) acetate wherein the blending composition comprises an impact polypropylene, impact modifier and plasticizer. The polypropylene, impact modifier and plasticizer are selected to meet requirements of flexible thermoplastic compositions useful in vehicle interiors. In another embodiment of the invention a random polypropylene is used.Type: GrantFiled: April 4, 2001Date of Patent: October 11, 2005Assignee: Sunoco Inc. (R&M)Inventor: Sehyun Kim

Patent number: 6890982Abstract: Waxes prepared from hydrogenated plant oils, such as palm and soybean, are used as substitutes for petroleum derived waxes in hot-melt adhesive compositions. Unlike petroleum-derived or synthetic waxes, adhesive compositions comprising these waxes, which are obtained from naturally derived, renewable resources, achieve adhesion performance similar to conventional adhesives containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-165 degrees F. (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acids are predominantly stearic acid (C18). The naturally derived waxes are used as an alternative to petroleum and synthetically derived waxes in the manufacture of adhesives used to bond paper, wood, glass, plastic and metal in a variety of manufacturing operations.Type: GrantFiled: June 11, 2002Date of Patent: May 10, 2005Assignee: Marcus Oil and Chemical-Corp.Inventors: Gregory Borsinger, Aziz Hassan
