Description

technical field

[0001] The invention relates to a polyester hot-melt adhesive composition, especially a polyester hot-melt adhesive composition with low melting viscosity. Background technique

[0002] Currently known polyester hot melt adhesives all use aromatic dibasic acids (or dimethyl dibasic acid) such as terephthalic acid and long carbon chain aliphatic dibasic acid (or dimethyl dibasic acid), dibasic acid dimethyl Alcohols are obtained after esterification (or transesterification) and polycondensation. For example, US Pat. No. 6,255,443 discloses a low melting point copolyester and polyether ester hot melt adhesive.

[0003] However, because the apparent viscosity of such polyester hot melt adhesive products is generally high, it is difficult to perform fast and uniform coating, thereby affecting the coating speed and increasing the coating amount. Contents of the invention

[0004] The object of the present invention is to provide a polyester hot-melt adhesive c...
