Persian gum (PG), as a recently-highlighted carbohydrate natural polymer, was introduced both as a powder adhesive in its pristine form, and as a water-redispersing agent for water-incompatible acrylic adhesives. Blends of PG and poly(methyl methacrylate-co-butyl acrylate) containing 30 wt. % methyl methacrylate (MBC) were molecularly incompatible at PG contents below 50 wt. % due to the large difference in their Hildebrand solubility parameters (calculated to be 37.49 and 19.71 J^1/2/cm^3/2 for PG and MBC, respectively). However, further increase in the PG content evolved the system toward miscibility through intensified intermolecular hydrogen bonds. Addition of PG to MBC at compositions of more than 50 wt. % PG also provided it with powderability. Swelling of slabs of the blends in water followed a pseudo-Fickian mechanism and the equilibrium swelling ratio of the blends was a reciprocal power function of ternary interaction parameter (${\chi }_{1(23)}$). Furthermore, increase in the PG content from 0 to 90 wt. % improved the adhesion strength of the blend adhesives. Ultimately, the blend containing 90 wt. % PG presented 52 times and 34 times enhancement in the adhesion strength to fabric and wood substrates compared to the pristine acrylic adhesive, respectively.

波斯树胶 (PG) 作为最近备受关注的碳水化合物天然聚合物，既可作为原始形式的粉末粘合剂，又可作为水不相容丙烯酸粘合剂的水再分散剂。PG 和聚（甲基丙烯酸甲酯-共-丙烯酸丁酯）的共混物，含有 30 重量份。% 甲基丙烯酸甲酯 (MBC) 在 PG 含量低于 50 wt 时在分子上不相容。% 由于它们的 Hildebrand 溶解度参数差异很大（计算为 37.49 和 19.71 J ^1/2 /cm ^3/2分别为 PG 和 MBC）。然而，PG 含量的进一步增加通过增强的分子间氢键使系统向混溶性发展。将 PG 添加到 MBC 中，组成超过 50 重量％。% PG 还赋予它粉化性。共混物在水中的膨胀遵循伪菲克机制，共混物的平衡溶胀比是三元相互作用参数的倒数幂函数（${\chi }_{1(23)}$）。此外，PG 含量从 0 增加到 90 重量％。% 提高了共混粘合剂的粘合强度。最终，共混物含有 90 重量。与原始丙烯酸粘合剂相比，% PG 对织物和木材基材的粘合强度分别提高了 52 倍和 34 倍。
