HOT MELT ADHESIVE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a hot melt adhesive composition capable of well adhering polyolefin substrates to each other or a polyolefin substrate to various different materials. SOLUTION: This hot melt adhesive composition comprises a modified polyolefin resin (A). The resin (A) is obtained by graft-modifying a polyolefin resin with an unsaturated carboxylic acid and/or its derivative. The resin (A) contains 0.1-50 wt% of the unsaturated carboxylic acid and/or its derivative and has weight-average molecular weight of 15,000-200,000. COPYRIGHT: (C)2005,JPO&NCIPI
