摘要
Polyhydric alcohol rosin esters which had been modified with an aromatic dibasic acid such that the softening point of the acid-modified polyhydric alcohol rosin ester is higher than that of a comparable unmodified polyhydric alcohol rosin ester are used as tackifiers in hot melt adhesive compositions. The hot melt adhesives compositions which utilize the acid-modified rosin ester tackifiers contain at least one of an ethylenic copolymer and a styrenic block copolymer, at least one of a wax and an oil, and the acid-modified polyhydric alcohol rosin ester tackifier. The hot melt adhesive compositions may be used as, for example, hot melt carton and package sealing adhesives, sealants, bookbinding adhesives, assembly adhesives, and are useful for the assembly of disposable articles using multiline construction techniques wherein at least one polyethylene or polypropylene substrate is bonded to at least one tissue, non-woven, polyethylene or polypropylene substrate.
