Poly(ethylene-co-1,2-butylene)diol
Poly(ethylene-co-1,2-butylene)diol (CAS 68954-10-9) is a diol polymer with an average molecular weight of approximately 2,500 g/mol. This hydrophobic polymer enhances the adhesion of polyolefins and modifies the surfaces of nonpolar polymers. It is also effective in improving the dispersibility of inorganic fillers within organic polymer matrices and imparts improved hydrophobic characteristics to urethanes and polyesters. Its good compatibility with polyolefins and rubbers makes it a versatile material in polymer science and materials applications.
