| 結(jié)果表明:當(dāng)溶劑為二氯甲烷時,比為甲苯時樹脂的軟化點高50℃左右。制備的間戊二烯樹脂軟化點最高為139℃,是目前報道的間戊二烯樹脂中軟化點最高的。樹脂的軟化點隨反應(yīng)溫度的升高而升高,而隨催化劑用量增加變化很小。 |
| The result shows that the softening point of resin in the dichloromethane solution is higher 50oC than in the methylbenzene solution. The maximum softening point of prepared pentadiene resin reached 139oC which was the highest value in this area. The resin softening point increased as increase of temperature as well as slightly decreased as increase of catalyst amount. |

| The results showed that softening point of the resin was 50 oC higher using methyllene chloride as solvent instead of toluene. The prepared 1,3-pentadiene resin had a softening point up to 139 oC, which is the highest among current reports. The softening point of the resin increased with the increase of reaction temperature, but only changed slightly with the increased amount of catalyst. |
