Abstract
Description
98%(5グラム(g))の1,4−cis含量を有するポリブタジエンゴムを、100ミリリットル(mL)のジクロロメタンに溶解し、5%(w/v)エラストマー溶液を得た。次に、40質量%のm−クロロペルオキシ安息香酸(m−CPBA)を溶液に加え、反応混合物を室温で3時間、攪拌した。完了後、反応混合物を炭酸ナトリウム(Na2CO3)又は重炭酸ナトリウム(NaHCO3)水溶液を用いてクエンチ処理した。有機層及び水層を分液漏斗で分離した。有機層を、メタノールに1:2(反応混合物/メタノール、容積/容積(v/v))の比で攪拌しながら注いだ。沈殿が形成され、これを濾過し、乾燥させた。
トルエン中、2%(w/v)のエポキシ化エラストマー溶液を調製した。1−プロパンチオールの40質量%(w/w)メタノール溶液、及びメタノール中、1モーラーのテトラブチルアンモニウムヒドロキシド(TBAH)溶液を、トルエン溶液に加えた。反応混合物を、23℃で72時間、攪拌し、次に、メタノールに注いだ。沈殿が形成され、これを濾過し、23℃で乾燥させた。濾過生成物を、1H NMR及び赤外線(IR)分光法によって特徴付けした。
THF溶媒中、2%及び4%(w/v)の両方のエポキシ化エラストマー溶液を調製した以外は実施例2の手順に従った。官能化エラストマー沈殿物の試料を、1H NMR分光分析法によって24時間の間隔で特徴付けした。次に、得られた官能化の割合を、図4に示されるように、時間経過を追ってプロットした。この試験結果は、濃度が増加するに従い、反応が速くなることを示している。結果はまた、時間経過に伴い、官能化が増加することも示している。
テトラヒドロフラン中、実施例1で用いたブタジエンゴムの5%(w/v)溶液を調製し、次に、m−CPBAを溶液に加えて、60%のMCPBA/エラストマー(w/w)濃度を達成した。反応混合物を、23℃で3時間、攪拌した。該反応混合物を、メタノール中、1.5モーラーのTBAH溶液を加えることによってアルカリ性にした。この混合物に、1−プロパンチオールを加えて、30%のプロパンチオール/エラストマー(w/w)濃度を達成した。反応混合物を50〜55℃で7時間、攪拌し、次に、反応混合物を23℃の温度とし、メタノールに注いだ(1/2.5の反応混合物/メタノール比、v/v)。沈殿物が形成され、これを単離して、23℃で乾燥させた。
