自由基聚合（Radical Polymerization）是一種通過自由基中間體進行的鍊式聚合反應，是合成高分子聚合物最重要和最常用的方法之一。其核心在于利用自由基（帶有未成對電子的高活性原子或基團）引發單體分子中的雙鍵或環狀結構打開，形成新的自由基并持續增長，最終生成高分子鍊。以下是詳細解釋：
鍊引發（Initiation）
反應由引發劑（如過氧化物、偶氮化合物）受熱或光照分解産生初級自由基開始。該自由基進攻單體（如乙烯、苯乙烯）的雙鍵，形成單體自由基：
$$ce{ I -> 2R• }$$
$$ce{ R• + CH2=CHX -> R-CH2-CHX• }$$
引發劑的選擇直接影響聚合速率和聚合物結構 。
鍊增長（Propagation）
單體自由基持續與新的單體分子加成，使鍊不斷延長。該階段反應速率快，分子量迅速增加：
$$ce{ R-CH2-CHX• + nCH2=CHX -> R-(CH2-CHX)_n-CH2-CHX• }$$
增長過程受單體濃度、溫度及自由基活性的影響 。
鍊終止（Termination）
兩條自由基鍊通過偶合終止（兩鍊結合）或歧化終止（氫原子轉移形成飽和/不飽和端基）失去活性：
$$ce{ 2R-(CH2-CHX)_n• -> R-(CH2-CHX)_n-(CHX-CH2)n-R quad (偶合)}$$
$$ce{ -> R-(CH2-CHX){n}CH2-CH2X + R-(CH2-CHX)_{n}CH=CHX quad (歧化)}$$
終止方式影響聚合物端基結構和分子量分布 。
自由基聚合廣泛用于工業生産常見聚合物，例如：
Radical Polymerization（自由基聚合）是一種通過自由基（含未成對電子的活性中間體）引發并傳遞鍊式反應的聚合方式。以下是詳細解釋：
自由基聚合是高分子工業中應用最廣泛的聚合方法之一，因其操作簡便且適用性廣，但需通過技術改進（如活性自由基聚合）提升控制精度。
