Abstract

Official abstract text for this publication.

The present invention provides a hot melt adhesive being highly environmentally-friendly, and as well having sufficient pressure-sensitive adhesiveness, adhesion, thermal stability and the like. The present invention relates to a hot melt adhesive comprising (A) a polar functional group-modified polymer, (B) an aliphatic polyester-based resin, (C) a tackifier resin and (D) a thermoplastic elastomer.

First claim

Opening claim text (preview).

The invention claimed is: 1. A hot melt adhesive comprising: (A) a polar functional group-modified polymer selected from a polar functional group-modified polyolefin-based polymer, (B) an aliphatic polyester-based resin, (C) a tackifier resin, and (D) a thermoplastic elastomer. 2. The hot melt adhesive according to claim 1 , further comprising a polar functional group-modified conjugated diene-based polymer. 3. The hot melt adhesive according to claim 1 , wherein the polyolefin-based polymer is an ethylene or an alpha-olefin having 3 to 20 carbon atom. 4. The hot melt adhesive according to claim 1 , wherein the polar functional group-modified polyolefin-based polymer is copolymerized with unsaturated carboxylic acid or derivatives thereof. 5. The hot melt adhesive according to claim 4 , wherein the unsaturated carboxylic acid is a vinyl carboxylate. 6. The hot melt adhesive according to claim 5 , wherein the vinyl carboxylate is methyl acrylate. 7. 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 mixture thereof. 8. The hot melt adhesive according to claim 1 , wherein the aliphatic polyester-based resin (B) is at least one selected from a polylactic acid-based resin, a poly(butylene succinate) and a polyhydroxybutyrate. 9. The hot melt adhesive according to claim 1 further comprising a plasticizer (E). 10. An article comprising the hot melt adhesive of claim 1 . 11. The article of claim 10 , which is a disposable product.
