<p>The present invention provides pressure sensitive adhesives, compositions from which the pressure sensitive adhesives are formed, and articles having therein these pressure sensitive adhesives. The pressure sensitive adhesives, which have a Tg of less than about 20 °C, include a poly(β-hydroxyorganoate) or mixture thereof. Preferably, these poly(β-hydroxyorganoate)s include monomeric units of general formula (I), wherein a minor amount (preferably no greater than about 20 mole percent) of the monomeric units have an R group containing 1-3 carbon atoms; and a major amount (preferably at least about 80 mole percent) of the monomeric units have an R group containing 4-30 (preferably 4-20) carbon atoms.</p> |
