Crosslinkable or Curable Polylactone Compositions, Polylactone-based Crosslinked Curable Forms and Polylactone Crosslinked or Curable Forms

摘要

A crosslinkable monomer (B) 0.1 capable of constraining the molecular chain of polylactone (A) by irradiation of active energy rays or by heating with respect to 100 parts by weight of polylactone (A) having a number average molecular weight in the range of 10,000 to 300,000. A polylactone crosslinked product which is crosslinked with a crosslinked polylactone composition comprising 30 parts by weight and the crosslinkable polylactone composition is melted and molded at an uncrosslinked temperature and then irradiated with active energy rays or heated. The manufacturing method of the above, and the polylactone crosslinked molded object obtained above are provided. Moreover, from the curable polylactone composition which consists of polylactone or polylactone composition (X) which consists of predetermined polylactone (C) and polyhydric alcohol (D), and a predetermined hardening | curing agent (Y), the curable poly which has the same property Lactone system shaped bodies are obtained.;The resulting molded article is biodegradable and has excellent physical properties such as mechanical strength, heat resistance, oil resistance and abrasion resistance compared to uncrosslinked or uncured polylactone, and deforms while exhibiting rubber elasticity when external force is applied during heating softening. If it is cooled and solidified according to the deformation, it retains its deformation shape, but if it is heated and softened again, it has the shape memory to restore to the shape of the initial molded body. It can be used for casts and the like.
