Description
さらに処分されずに投棄された発泡体が及ぼす、河川、海洋など、自然態系への影響も無視できなくなってきている。そこで、生態系の中で分解し、地球環境への影響が少ない樹脂が開発された。例えば、微生物の体内で合成されるポリヒドロキシブチレート系樹脂や、脂肪族グリコールと脂肪族カルボン酸からなるポリエステル又は、カプロラクトンを主成分とするポリエステル系樹脂などが発表されているが、前者は、微生物が作り出すため、極めて生産性が悪く、利用は制限される。 Furthermore, the impact on natural systems such as rivers and oceans caused by foams that are dumped without being disposed of can not be ignored. Therefore, resins that decompose in the ecosystem and have less impact on the global environment were developed. For example, polyhydroxybutyrate-based resins synthesized in the body of microorganisms, polyesters composed of aliphatic glycols and aliphatic carboxylic acids, and polyester-based resins composed mainly of caprolactone have been described, but the former is Because the microbes produce, their productivity is extremely poor and their use is limited.
