摘要
Polytetrahydrofuran is a key material for synthesizing spandex and PU elastomer,and it can give the product excellent performance.The economics situation at home and abroad and production processes of polytetrahydrofuran are introduced in detail.At present,as catalyst for synthesizing polytetrahydrofuran solid acid is mainly used due to its advantages such as lower corrosion,non- pollution,easier regeneration and controllable product molecular weight and its distribution.
