Crosslinked or hardened polylactone based composition, polylactone crosslinking or curing molding, and method for producing polylactone crosslinking or cured molding

摘要

A cross-linked monomer (b) 0 which can bind the molecular chain of polylactone (a) by irradiation of an active energy beam or heating to 100 parts of the polylactone (a) having a number average molecular weight of 10000 to 30000.A crosslinkable polylactone based composition comprising 1 to 30 parts by weight, a crosslinked polylactone based composition, which is fused to a temperature at which no crosslinking is applied to the crosslinked polylactone based crosslinking material after curing with active energy lines or crosslinking by heating The molding method and the polylactone based crosslinking molded product are provided. A curing polylactone based composition comprising a polylactone or a polylactone composition (x) comprising a predetermined polylactone (c) and a polyvinyl alcohol (d) and a predetermined curing agent (y) is also obtained from a curing polylactone type molded body having similar properties . These molded bodies have biodegradability and are excellent in various properties such as mechanical strength, heat resistance, oil resistance, and abrasion resistance compared with uncrosslinked or uncured polylactone, and when the external force is applied in the softening, the deformation is deformed while the rubber elasticity is shown, and is changed Shape memory to reshape the shape of an earlier molded body when it is heated and softened as it is solidifiedSince it has sex, it can be used for a patient fixed sheet for radiotherapy, an action type material for wig, a toothed material, a Gibbs, etc.
