Polybutylene succinate

In that time the Portuguese professor Agostinho Vicente Lourenço described in his "Recherche sur les composés polyatomiques" (Research on polyatomic compounds), the reaction between succinic acid and ethylene glycol to form what he named "succino-ethylenic acid".

He noticed that this acid was losing water when it was heated at high temperatures (300 °C) and that a crystalline mass when obtained after cooling.

du Pont de Nemours and Co.), with a more systematic study of succinic acid based polyesters.

Carothers, by eliminating water in a continuous distillation process, obtained polymers with molar masses significantly higher than what was previously synthesized.

[9] As PBS decomposes into water and CO2 through naturally occurring degrading enzymes and microorganisms,[10] it may be a biodegradable alternative to some common plastics.

In agriculture, PBS finds interest in the fabrication of mulching films or delayed release materials for pesticide and fertilizer.

PBS is also promise to find market shares in fishery (for fishing nets), forestry, civil engineering or other fields in which recovery and recycling of materials after use is problematic.

[13] Sold under the tradename Bionolle, these polyesters are synthesized via melt condensation polymerization followed by a chain-extension with a diisocyanate.

[14] Much later, in April 2003, Mitsubishi Chemicals built a 3,000 tons/year capacity and launched to the market a PBS named GS Pla (Green and Sustainable Plastic).

The same year Xinfu Pharmaceutical announced the building up of the world's largest continuous PBS production line with an annual capacity of 20,000 tons.
