摘　　要：以二乙醇胺、丙烯酸甲酯、三羟甲基丙烷以及环氧氯丙烷为原料,合成不同代数的端环氧基超支化聚(胺-酯)(EHPAE)。其后,以从制革废弃物中提取的明胶为原料,不同代数的EHPAE分别作为交联单体进行改性,制得一种环保型鞋用或包袋用胶粘剂。采用FTIR、1HNMR和GPC对超支化聚合物和胶粘剂的结构及相对分子质量分布进行表征,之后对胶粘剂的粘结性能进行测定,结果表明:EHPAE-Ⅲ较其余两者的改性效果更为明显,当EHPAE-Ⅲ用量为明胶质量的30%时,改性后胶粘剂的固含量由11.42%提高到了30.33%,同时剪切强度为2.216 MPa、T-剥离强度为3.375 N/mm、水接触角为100.9°,相较于市售胶粘剂的剪切强度(1.868 MPa)、T-剥离强度(2.864 N/mm)、水接触角(84.8°),制备得到胶粘剂的粘结性能和疏水性均更优。Epoxy-terminated hyperbranched poly(amine-ester)(EHPAE)samples with different generation were prepared from diethanolamine,methyl acrylate,trimethylolpropane and epoxy chloropropane.And then,an environmental-friendly of adhesives for footwear or bags were synthesized using gelatin extracted from leather wastes as main material,different generation of EHPAE samples as cross-linking monomer,respectively.The structure and relative molecular mass distribution of hyperbranched polymers and adhesive were characterized by FTIR,1 HNMR and GPC.Moreover,the bonding performances of the adhesive was measured.The results showed that EHPAE-III exhibited better modification effect than the other two.When the dosage of EHPAE-Ⅲwas 30%(based on the mass of gelatin),the solid content of the modified adhesive was increased from 11.42%to 30.33%.Meanwhile,the shear strength and T-peel strength of the prepared adhesive were 2.216 MPa and 3.375 N/mm,respectively.The water contact angle was 100.9°.While the commercial available adhesive showed shear strength,T-peel strength and water contact angle of 1.868 MPa,2.864 N/mm and 84.8°.It was found that the prepared adhesive had better adhesive properties and hydrophobicity than the commercial available adhesive.
