Synthesis of star polymers applicable as filler for polyurethane coatings by ionic polymerization

Abstract

Star polymers were prepared by ionic polymerization. As the star core polyols served e.g.: trimethylol propane (TMP), pentaerythrythol (PETP) and dipentaerythrythol (DPETP) and the star arms were built up from ε-caprolactame, lactide in different ratios of both components. Coatings based on TMP have often anti-slip properties high gloss but lower hardness. On the contrary, coatings based on PETP and DPETP have high hardness, but no anti-slip properties.
