Abstract:
This invention relates to a catalyst for alkylating polyalkylene glycol and a method of alkylating polyalkylene glycol using the same, wherein the catalyst enables polyalkylene glycol to be alkylated at a high conversion rate without generating harmful materials and the terminal of polyalkylene glycol can be alkylated using the same. Thereby, the terminal of polyalkylene glycol can be alkylated in an environmentally friendly and economical manner through a simple process.
