Propargyl-PEG5-alcohol（CAS#87450-10-0）

Introduction

Propynyl-tetraethylene glycol, also known as polypropynyl alcohol, is a polymer containing propynyl functional groups. The following is an introduction to the properties, uses, preparation methods and safety information of propynyl-tetrameric glycol:

Quality:

- Propynyl-tetraethylene glycol is a colorless to yellowish liquid or solid.

- It has good solubility and is soluble in most organic solvents and water.

Use:

- It can be used as a polymer modifier, viscosity modifier, impregnation agent and thickener, etc.

Method:

- Proynyl-tetraethylene glycol can be synthesized in a two-step process, where propynyl functional groups are first introduced into the polyethylene glycol chain using a propynylating agent, followed by polymerization.

- Polymerization reactions are typically catalyzed by metal catalysts such as silver or platinum salts.

Safety Information:

- Propynyl-tetraethylene glycol is flammable and should be avoided from contact with open flames or high-temperature substances.

- Wear appropriate protective gloves and eyes to avoid skin contact and inhalation when operating.

- Should be stored in a cool, well-ventilated place and away from oxidizing agents.

- When using and handling propynyl-tetrameric glycol, safe operating procedures and relevant regulations should be observed.
