Polymer為英語名詞,音標英[ˈpɒlɪmə(r)]、美[ˈpɑːlɪmər],指由重複結構單元通過化學鍵連線形成的高分子聚合物,複數形式為polymers,偶作姓氏使用。
該術語涵蓋天然與合成材料兩大類,其分子結構特性使其廣泛套用於化工製造、材料工程及高分子科學領域,相關概念包括高分子鏈、結晶聚合物等。學科分支涉及聚合物化學、功能高分子研究等,常用複合詞組如高分子材料(polymer material)反映其工業套用屬性。
高分子概念的起源可追溯至19世紀對天然橡膠和纖維素的化學研究。20世紀合成化學發展推動尼龍、聚乙烯等人工聚合物誕生,現代高分子科學逐步形成分子設計及聚合反應機理等理論體系,套用領域擴展至生物醫用材料及日常塑膠等。
