  The study of amalgamation in the category of partially ordered monoids was
initiated by Fakhuruddin in the 1980s. In 1986 he proved that, in the category
of commutative pomonoids, every absolutely flat commutative pomonoid is a weak
amalgmation base and every commutative pogroup is a strong amalgamation base.
Some twenty years later, Bulman-Fleming and Sohail in 2011 extended this work
to what they referred to as pomonoid amalgams. In particular they proved that
pogroups are poamalgmation bases in the category of pomonoids. Sohail, also in
2011, proved that absolutely poflat commutative pomonoids are poamalgmation
bases in the category of commutative pomonoids. In the present paper we extend
the work on pomonoid amalgams by generalising the work of Renshaw on amalgams
of monoids and extension properties of acts over monoids.
