demonstrate the superiority of examples 1 3 versus the comparative examples 1 4 important properties such as saft are significantly higher with the adhesives made by the teachings of this invention saft is an important test for determining storage of adhesive bonds under a static load under elevated temperatures such as those encountered during the shipment of finished disposable articles the examples of this invention possess superior high temperature properties as evidenced by the saft and static shear results and superior adhesion to hdpe at 4 u00b0 c the static shear properties are especially greater for example 1 versus any of comparative examples 1 4 even example 3 which was formulated to be lower in viscosity compared to examples 1 2 has comparable properties versus the comparative examples lower viscosity hot melts are beneficial for bonding thinner polyolefin films to nonwovens for the manufacture of disposable articles without distortion of the substrates concerning property retention after exposure to elevated temperatures the adhesives of this invention overcome the limitations of both styrene isoprene and styrene butadiene copolymers by blending them this blend provides a more stable adhesive versus an adhesive formulated with either copolymer alone styrene isoprene copolymer based adhesives undergo chain scission which lowers the molecular weight of the copolymer and weakens the adhesive resulting in lower heat and shear resistance adhesives formulated with styrene butadiene copolymers undergo chain extensions during exposure to elevated temperature which leads to the gelation of the adhesive that can plug application equipment now that the preferred embodiments of the present invention have been described in detail various modifications and improvements thereon will become readily apparent to those skilled in the art accordingly the spirit and scope of the present invention is.
