Concerns about health effects caused by low levels of residual monomers in PVC and acrylonitrile resins promoted the consideration of condensation polymers such as poly(ethylene terephthalate) (PET) (41). Packaging resins based on acrylonitrile are extraordinarily good barriers that were considered for carbonated beverage bottles. The furor over residual monomers in these materials stunted their growth in spite of improved technology to reduce residuals to barely detectable levels. The step reaction polymer, polyethylene terephthalate(PET) has intrinsically much lower residual monomers in the as-made polymer, and it has become the material of choice for the carbonated beverage market (42).

A modified release system for the herbicide ametryn was developed by Grillo and co-workers [24] via encapsulation of the active substance in polymer P(3HB) and poly(3HB-co-3HV) microparticles in order to improve the herbicidal action and minimise environmental impact. Nearly 100% release of free ametryn was observed after 1.2 days compared with a significantly reduced herbicide release, 75 and 87% respectively, over the same period of time for P(3HB) and poly(3HB-CO-3HV) microparticles. A slower and more sustained release is a desirable feature in the use of herbicides as it diminishes the impact on the ecosystem, human health and environment. Prudnikova and co-workers [25] presented the first report of the use of PHA/ herbicide matrices to kill weeds. They reported that the herbicide Zellek Super, loaded into copolymer poly(3HB-co-3HV) carriers, was more effective than when it was applied traditionally as a spray onto plants during the tillering phase. However, the inhibitory effect on soil microorganisms was reduced by the encapsulation of the herbicide in the polymer matrix but its effectiveness against test plants was maintained.
