NON-CROSSLINKED, CROSSLINKABLE POLYURETHANE

A non-crosslinked, crosslinkable polyurethane has an acid number of 20-40 and a glass transition temperature of up to and including 40° C. It can be derived from an aromatic diisocyanate; and a diol mixture of at least D1, D2, D3, and D4 diols. D1 has a C3 to C7 aliphatic group and at least one pend...

Zusammenfassung:	A non-crosslinked, crosslinkable polyurethane has an acid number of 20-40 and a glass transition temperature of up to and including 40° C. It can be derived from an aromatic diisocyanate; and a diol mixture of at least D1, D2, D3, and D4 diols. D1 has a C3 to C7 aliphatic group and at least one pendant carboxy group or pendant neutralized carboxy group. D2 has a chain of repeating C2 to C6 alkylene oxide groups and a molecular weight of 250-3000. D3 is an alkoxylated bisphenol A or aliphatic cyclic diol present in an amount of at least 5 mol %. D4 is a hydroxy-terminated polybutadiene having a molecular weight of at least 1000, and is present in an amount of at least 0.1-5 mol %.
