該反應為酸催化下的陽離子型縮聚反應。
縮聚反應（condensation polymerization）是一種通過單體分子間官能團縮合生成高分子聚合物的化學過程。該反應過程中，單體之間通過脫去小分子副産物（如水、醇或氯化氫等）形成共價鍵，逐步增長為長鍊聚合物。例如，聚酯和尼龍的合成均屬于典型的縮聚反應（來源：美國化學會ACS）。
縮聚反應的核心機制涉及兩個或更多官能團的相互作用。例如，羧酸與醇反應生成酯鍵時，會脫去一分子水。這種逐步聚合的特點使得分子量隨時間緩慢增加，最終産物的分子量分布較寬（來源：英國皇家化學會RSC）。常見的縮聚反應類型包括聚酯化反應（如PET塑料）和聚酰胺反應（如尼龍-6,6）。
該反應在工業中應用廣泛：
縮聚反應與加聚反應的關鍵區别在于副産物的生成，這一特性使其在可控合成功能高分子材料領域具有獨特優勢（來源：MIT開放式課程-高分子化學章節）。
Condensation polymerization（縮聚反應） 是一種通過單體分子間反複縮合生成高分子聚合物并伴隨小分子副産物（如水、醇等）的化學反應。以下是其核心要點：
定義與機理
縮聚反應中，單體通常含有兩個或以上可反應的官能團（如羧酸與醇、胺與羧酸等），通過脫去小分子（如H₂O、HCl）逐步連接成長鍊聚合物。例如，聚酯（如PET）的合成就是典型的縮聚反應。
特點
分類與實例
與加聚反應的區别
縮聚反應伴隨小分子釋放，而加聚反應（如聚乙烯的合成）無副産物，僅通過不飽和鍵打開連接。
