HOT MELT ADHESIVE COMPOSITION BASED ON A RANDOM COPOLYMER OF ISOTACTIC POLYPROPYLENE AND A SECONDARY POLYMER

摘要

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, about 0 % - 60 % by weight of an atactic poly-a-olefin (APAO), and about 0 % - 40 % by weight of a secondary polymer. 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.
