Polymer compositions comprising a polymer (A) having a repeating structure unit of the formula (I) in the main chain
wherein R¹, R², R³, R⁴, R⁵ and R⁶ are respectively a hydrogen atom or a lower alkyl, and at least one species selected from the group consisting of a phenol compound and a plasticizer. The polymer compositions of the present invention disintegrate themselves due to decomposition of the polymer (A) contained therein in atmosphere, soil or water and thus, they are useful as materials for disposable moldings.
聚合物组合物,其聚合物 (A) 的主链中含有式 (I) 的重复结构单元
其中 R¹、R²、R³、R⁴、R⁵ 和 R⁶ 分别为氢原子或低级烷基,以及至少一种选自苯酚化合物和增塑剂组成的组的物质。本发明的聚合物组合物在大气、土壤或水中会因所含聚合物(A)的分解而自行解体,因此可用作一次性模塑材料。
