Polyester compositions comprising dimer acid or dimer acid alkyl ester preparation method thereof and hot-melt adhesive containing the same

摘要

(a) at least one dimer acid or alkyl ester thereof; (b) aromatic dicarboxylic acids, diesters of aromatic dicarboxylic acids, anhydrides of aromatic dicarboxylic acids, heteroaromatic dicarboxylic acids, diesters of heteroaromatic dicarboxylic acids and heteroaromatic dicarboxylic acids At least one monomer selected from the group consisting of anhydrides; (c) at least one diol monomer; And (d) a thermoplastic polyester obtained by the polymerization of at least one epoxidized vegetable oil, wherein the (d) epoxidized vegetable oil is 1 to the total weight of (a), (b), (c) and (d). To 16 parts by weight of thermoplastic polyester is disclosed. The thermoplastic polyester is manufactured using dimer acid or alkyl esters thereof and epoxy vegetable oils, so it is more environmentally friendly than conventional petroleum based polymer elastomers. In addition, there is an effect of reducing the cost of the raw material in terms of economics than petroleum-based polyester. Furthermore, the thermoplastic polyester is not only applicable to hot melt adhesives, paints, coatings, etc., but also exhibits excellent tensile, toughness and hydrolytic stability, weather resistance, and adhesive strength, thereby exhibiting excellent performance as a hot melt adhesive.
