Methods of forming acrylic acid from a PHA, such as, for example, poly 3-hydroxypropionate
or a 3-hydroxypropionate containing polymer are disclosed. The methods can include,
for example, heating a biomass containing the PHA to form acrylic acid. The methods
can include, for example, heating the PHA to a temperature of at least about 200
C. to form acrylic acid. The methods can include for example, heating a mixture
containing a first portion of the PHA to form a first portion of acrylic acid,
and then adding a second portion of the PHA to the mixture.
