manufacture example 1
[0281] [Single-terminal acid-modified ethylene-propylene random copolymer (a-1)]
[0282] Put the low molecular weight ethylene-propylene random copolymer obtained by the thermal degradation method into a stainless steel pressure-resistant reaction vessel equipped with a stirrer, a thermometer, a heating and cooling device, a nitrogen gas introduction pipe and a decompression device [the ethylene-propylene random copolymer (Propylene content = 33 mol%) was obtained by performing thermal degradation at 410±0.1° C. under a nitrogen atmosphere (80 mL / min) for 16 minutes. Mn: 3,900, average number of double bonds per molecule: 1.0] 90 parts, 10 parts of maleic anhydride, and 30 parts of xylene were uniformly mixed, replaced with nitrogen, and heated to 200° C. while stirring under airtight conditions. It melted and reacted at this temperature for 10 hours. Next, under reduced pressure (below 0.013MPa), excess maleic anhydride and xylene were distilled off at 200°C for 3 hours to...

[0287] [Single-end acid-modified 1-butene-propylene random copolymer (a-3)]
[0288] Put the low molecular weight 1-butene-propylene random copolymer obtained by the thermal degradation method into a stainless steel pressure-resistant reaction vessel equipped with a stirrer, a thermometer, a heating and cooling device, a nitrogen gas introduction pipe and a decompression device [the 1-butene - Propylene random copolymer (propylene content = 82 mol %) obtained by thermal degradation at 410±0.1° C. under nitrogen (80 mL / min) for 16 minutes. Mn: 3,900, average number of double bonds per molecule: 1.0] 90 parts, 10 parts of maleic anhydride, and 30 parts of xylene were uniformly mixed, replaced with nitrogen, and heated to 200° C. while stirring under airtight conditions. It melted and reacted at this temperature for 10 hours. Next, under reduced pressure (below 0.013MPa), excess maleic anhydride and xylene were distilled off at 200°C for 3 hours to obtain a single-terminal acid...
