降冰片烯类、六氟丙烯和2,5-二氢-2,5-二甲氧基呋喃三元共聚方法
摘要：
本发明涉及到一种降冰片烯类、六氟丙烯和2,5-二氢-2,5-二甲氧基呋喃三元共聚方法，其特征在于包括下述步骤：按照摩尔比1∶1：1取聚合单体降冰片烯类、六氟丙烯和2,5-二氢-2,5-二甲氧基呋喃加入到高压釜中，加入溶剂溶解；然后加入引发剂，在80～150℃、1～3MPa压力下反应1～4小时；所述引发剂包括过氧化二叔丁基和过氧化乙酸叔丁酯，过氧化二叔丁基和过氧化乙酸叔丁酯的摩尔比为0.1∶1～1∶0.1；所述引发剂的用量为聚合单体总重量的0.1％～1.5％；将反应得到的产物倒入含乙醇溶液中，得到的沉淀物用乙醇洗涤，真空干燥后即得到降冰片烯类、六氟丙烯和2,5-二氢-2,5-二甲氧基呋喃三元共聚物。
摘要（英）：

The invention relates to a norbornene, hexafluoropropylene and 2,5-dihydro-2,5-dimethoxy furan ternary polymerization method. The norbornene, hexafluoropropylene and 2,5-dihydro-2,5-dimethoxy furan ternary polymerization method is characterized by comprising the following steps: adding polymerization monomer norbornene, hexafluoropropylene and 2,5-dihydro-2,5-dimethoxy furan into a high-pressure kettle in a molar ratio being 1 to 1 to 1, and adding a solvent to dissolve; adding an initiator, reacting for 1-4 hours at a temperature being 0-150 DEG C under pressure being 1-3 MPa, wherein the initiator is prepared from di-tert-butyl peroxide and tert-butyl peroxyacetate in a molar ratio being (0.1:1) to (1:0.1), and dose of the initiator accounts for 0.1%-1.5% of the total weight of the polymerization monomer; pouring the product obtained by reaction into an alcohol containing solution, washing obtained precipitates with alcohol, and vacuum-drying to obtain the norbornene, hexafluoropropylene and 2,5-dihydro-2,5-dimethoxy furan ternary polymer.
