Synthesis and properties of f-CTBN/PEG polyurethane materials
A series of novel highly-branched polyurethanes (PUR) were established and polymerized on the basis of the triethanolamine-hyperbranched carboxyl-terminated poly ( butadiene-co-acrylonitrile) (/-CTBN) and poly ( ethylene glycol) (PEG) with step-by-step synthetical method. The material properties of amount of /-CTBN and PEG and curing agent (HDI and H12MDI). Micrograph, mechanical properties and toxicity test used to evaluate. Those results showed PUR at the m(f-CTBN)/m(PEG) 3:7 will have been becoming medical film products in the biomedical field.
