Abstract

Official abstract text for this publication.

The present invention provides a hot melt adhesive being highly environmentally-friendly, and as well having sufficient tackiness, adhesion, thermal stability and the like. 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, and (C) a tackifier resin.

First claim

Opening claim text (preview).

The invention claimed is: 1. A hot melt adhesive comprising: (A) a polar functional group-modified conjugated diene-based polymer, (B) an aliphatic polyester-based resin, and (C) a tackifier resin, wherein the aliphatic polyester-based resin (B) comprises at least one selected from a polyactic acid-based resin, a poly(butylene succinate) and a polyhydroxybutyrate. 2. 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 imino group, an alkoxysilyl group, a silanol group, a silyl ether group, a hydroxyl group, an epoxy group, and mixtures thereof. 3. The hot melt adhesive according to claim 2 , wherein the polar functional group-modified conjugated diene-based polymer (A) comprises at least one polymer selected from an amino group-modified hydrogenated-type thermoplastic block copolymer and a maleic acid group-modified hydrogenated-type thermoplastic block copolymer. 4. The hot melt adhesive according to claim 1 further comprising a thermoplastic block copolymer (D). 5. The hot melt adhesive according to claim 1 further comprising a plasticizer (E). 6. A disposable product comprising the hot melt adhesive according to claim 1 .
