＜Example 1＞
The lubricity of various coatings was tested by varying the ratio of a toughening polymer (PMMA) to a lubricative polymer (poly(methyl vinyl ether-co-maleic anhydride)) in the top coating layer of a medical device.
polyurethane-tungsten jacketed nitinol wires
↓2.5% w/v aliphatic polyether-based polyurethane / THF
↓After the base layer was dried,
↓different top coatings
the maleic anhydride portion of the lubricative polymer to a maleic acid sodium salt.
＜Example 2＞
the lubricity increased with the addition of PMMA
＜Example 3＞
2.5% w/v an aliphatic polyether-based polyurethane/ THF
the same activation step
to convert the maleic anhydride portion of the lubricative polymer to a maleic acid sodium salt.
