丙烯酸酯的熱引發(fā)本體聚合-無法有效成型問題 已有1人參與
|

![]() 按照文獻所述的方法采用丙烯酸丁酯為單體,引發(fā)劑AIBN,引發(fā)劑用量0.5-2%,充分溶解 將混合溶液注入自制的玻璃模具中密封,在溫度60-70 ℃下反應(yīng),并不能發(fā)生完全聚合,得不到文獻所述的塊體聚合物 請問是什么原因 ![]() ![]() Ref. A Mechanically Robust, Self-Healing, and Adhesive Biomimetic Camouflage Ionic Conductor for Aquatic Environments “PILEs were synthesized through the polymerization of [ATAC][TFSI] and BA. Taking PILE-1 as an example, 1.752 g of [ATAC][TFSI] (equivalent to 4.0 mmol), 1.536 g of BA (equivalent to 12.0 mmol), and 0.033 g of thermal initiator AIBN were mixed and stirred. Subsequently, the mixed solution was injected into a glass mold and polymerized at 60 °C for 20 h to produce the PILE.” |

確定內(nèi)部溫度在60-70度?可以適當(dāng)升個10度再看看。內(nèi)部有一點點塊狀凝膠說明還是發(fā)生聚合了。 |
