ALKOX(R)
L Series (Patent Pending)
Introduction

ALKOX® L series are low molecular weight Poly (ethylene oxide) filing the gap between average molecular weight 50,000 ~ 100,000 manufactured by direct ring-opening polymerization with our state of the art catalyst technologies.

ALKOX® L Series have extremely narrow range and sharp molecular weight distribution compared with conventional poly(ethylene oxide) and have been expected to be utilized in versatile applications by future discovered characteristics.
