Abstract

Official abstract text for this publication.

The present invention provides a hot melt adhesive which is excellent in environmental friendliness, thermal stability, adhesion to a polyolefin substrate and a polyester substrate, and heat resistance. The present invention relates to a hot melt adhesive comprising (A) a polar functional group-modified conjugated diene-based polymer, (B) an aliphatic polyester-based resin, (C) an amorphous olefin-based polymer, (D) a crystalline polypropylene resin, and (E) a tackifier resin.

First claim

Opening claim text (preview).

What is claimed is: 1 . A hot melt adhesive comprising: (A) a polar functional group-modified conjugated diene-based polymer, (B) an aliphatic polyester-based resin, (C) an amorphous olefin-based polymer, (D) a crystalline polypropylene resin, and (E) a tackifier resin. 2 . The hot melt adhesive according to claim 1 , wherein the polar functional group-modified conjugated diene-based polymer (A) comprises at least one selected from an amino group-modified hydrogenated-type styrene block copolymer and a maleic acid group-modified hydrogenated-type styrene block copolymer. 3 . The hot melt adhesive according to claim 1 , wherein the aliphatic polyester-based resin (B) comprises a polylactic acid-based resin. 4 . The hot melt adhesive according to claim 1 , wherein the polar functional group is at least one functional group selected from an acid anhydride group, a maleic acid group, a carboxyl group, an amino group, an amino group, an alkoxysilyl group, a silanol group, a silylether group, a hydroxyl group, and an epoxy group. 5 . The hot melt adhesive according to claim 1 , wherein the amorphous olefin-based polymer (C) comprises an ethylene/propylene/1-butene copolymer. 6 . The hot melt adhesive according to claim 1 , wherein the amount of the crystalline polypropylene resin (D) is 3 to 30 parts by weight based on 100 parts by weight of the total weight of the components (A) to (E). 7 . An automotive interior material comprising the hot melt adhesive according to claim 1 . 8 . An automotive interior material comprising the hot melt adhesive according to claim 1 disposed on a polyolefin substrate or a polyester substrate. 9 . An automotive interior material comprising a polyolefin substrate or a polyester substrate bonded to an adherent by the hot melt adhesive according to claim 1 . 10 . An automotive interior material comprising a polyolefin substrate or a polyester substrate bonded to a fibrous adherent by the hot melt adhesive according to claim 1 .
