Patent number: 7271202Abstract: The invention is a reactive hot melt composition which has excellent adhesion and curing properties, and can be formulated into free-flowing pellets or beads, by using an ethylene-acrylic acid copolymer, and athylene-methacrylic acid copolymer, and/or an ethylene-acrylic acid methacrylic acid terpolymer as a component of the composition along with free radical crosslinking initiators. The incorporation of a foaming agent enables the production of compositions which are useful in space-filling applications, (i.e., as so-called “anti-flutter” compositions).Type: GrantFiled: February 23, 2004Date of Patent: September 18, 2007Assignee: Dow Global Technologies Inc.Inventors: Franciscus J. T. Krabbenborg, Marc A. Mangnus, Philippe C. Belot, Josiane Leon
