Surface characteristics of polyurethane networks based on polycaprolactone
Апстракт
A series of polyurethane networks (PUN) having different soft segment
content (SSC) was synthesized by the prepolymer method in solution, using
polycaprolactone diol as soft segment, and hyperbranched polyester and
isophorone diisocyanate (IPDI) as components of hard segments. FTIR
spectroscopy confirmed the structure of the prepared PUN. Furthermore, it
has been shown that swelling degree of PUN in tetrahydrofuran (THF) and
molecular weight of polymer chains between crosslinks (Mc) increase with
increasing SSC, while the opposite was observed for the crosslinking density
(ν) and percent of the water absorption.
