Embodiment 1
[0070] Take 76g of 1,8-octanediamine and 61g of 1,6-hexamethylenediamine, and add them to two 500mL three-neck flasks respectively, then add 48g of guanidine hydrochloride to each of the two flasks, and stir and Raise the temperature to 120°C, react for 4 hours, then combine the materials in the two flasks into one, and gradually raise the temperature to 170°C to continue the reaction for 1.5 hours, then add 54g of laurylamine, continue to react for 2 hours and then pour it out while it is hot. After cooling, the functional guanidine oligomer is obtained. Take 0.941 g of the guanidine oligomer and dissolve it in 5.23 g of methanol solvent (6.17 g in total) to obtain a solution of the functional guanidine oligomer.
[0071] The second step is similar to Comparative Example 1, using St, MMA, BA, and GMA as mixed monomers, wherein h, l, m, and k are respectively: 0.24, 0.165, 0.066, and 0.002. The mixed monomer was poured into a three-necked flask placed in a water bath together...
Embodiment 2
[0074] Take 76g of 1,8-octanediamine and 61g of 1,6-hexamethylenediamine, and add them to two 500mL three-necked flasks respectively, then add 48g of guanidine hydrochloride to each of the two flasks, and stir and Raise the temperature to 120°C, react for 4 hours, then combine the materials in the two flasks into one, and gradually raise the temperature to 170°C to continue the reaction for 1.5 hours, then add 54g of laurylamine, continue to react for 2 hours and then pour it out while it is hot. After cooling, the functional guanidine oligomer is obtained. 16.1 g of the guanidine oligomer was taken and dissolved in 89.44 g of dimethyl sulfoxide solvent (105.44 g in total) to obtain a solution of the functional guanidine oligomer.
[0075] The second step is similar to Comparative Example 1, using St, MMA, BA, and GMA as mixed monomers, wherein h, l, m, and k are respectively: 0.24, 0.165, 0.066, and 0.002. The mixed monomer was poured into a three-necked flask placed in a wa...
Embodiment 3
[0078] Get 97g of α, ω-tetraethylene glycol diamine and 44g of 1,4-butylene diamine, add respectively in two 500mL three-necked flasks, then respectively add 48g of guanidine hydrochloride in the two flasks respectively, under nitrogen atmosphere Under protection, stir and heat up to 120°C, react for 4 hours, then combine the materials in the two flasks into one, and gradually heat up to 170°C to continue the reaction for 1.5 hours, then add 87g of palmitamine, and continue the reaction for 2 hours Pour it out while it is hot, and get the functional guanidine oligomer after cooling. Take 1.049 g of the guanidine oligomer and dissolve it in 5.828 g of dimethylformamide solvent (6.877 g in total) to obtain a solution of the functional guanidine oligomer.
[0079] The second step is similar to Comparative Example 1, using St, MMA, BA, and GMA as mixed monomers, wherein h, l, m, and k are respectively: 0.24, 0.165, 0.066, and 0.002. The mixed monomer was poured into a three-necke...
