Description
該新規混合物に使用されるコポリマーは慣用の共重合方法、例えば懸濁重合、溶液重合、気相重合または高圧塊状重合によって製造することができる。好ましくは高圧塊状重合であり、この際この重合は、好ましくは、50〜400MPa、特に100 〜300MPaの圧力及び好ましくは50〜300 ℃、特に100 〜250 ℃の温度で行われる。各モノマーの反応は、遊離基を形成する開始剤（遊離基連鎖開始剤）によって開始される。この部類の物質には、例えば、酸素、過酸化水素類、過酸化物及びアゾ化合物、例えばクメンヒドロペルオキシド、t-ブチルヒドロペルオキシド、ジラウリルペルオキシド、ジベンゾイルペルオキシド、ビス（2-エチルヘキシル) ペルオキシドカーボネート、t-ブチルペルピバレート、t-ブチルペルマレエート、t-ブチルペルベンゾエート、ジクミルペルオキシド、t-ブチルクミルペルオキシド、ジ（t-ブチル）ペルオキシド、2,2'- アゾビス（2-メチルプロピオニトリル）及び2,2'- アゾビス（2-メチルブチロニトリル）が包含される。これらの開始剤は、各々単独かまたは２種以上のものの混合物として、モノマー混合物を基準として0.001 〜20重量％、好ましくは0.01〜10重量％の量で使用される。
