结果表明：当溶剂为二氯甲烷时,比为甲苯时树脂的软化点高50℃左右.制备的间戊二烯树脂软化点最高为139℃,是目前报道的间戊二烯树脂中软化点最高的.树脂的软化点随反应温度的升高而升高,而随催化剂用量增加变化很小.
答案
When dichloromethane is used as solvent,the softening point of resin is about 50 ℃ higher than using toluene.The highest softening point of the pentadiene resin produced is 139 ℃,Currently,it is the highest reported softening point.The softening point of resin goes up as the reaction temperature increases,and it drops as the amount of catalyst increases.
