Polylactic acid copolymer and method for producing same |
| abstract |
A polylactic acid copolymer having more improved hydrolizability and hydrophilic property than those of the polylactic acid. The polylactic acid copolymer is obtained by the copolymerization of a polylactic acid with an acid-releasing ester polymer capable of releasing an acid other than the lactic acid upon the hydrolysis. The polylactic acid copolymer has a quantity of heat of fusion ΔH of not more than 20 J/g as measured by using the DSC when the temperature is elevated the second time, contains the copolymer units stemming from the acid-releasing ester polymer in an amount of 0.5 to 35% by mass, and has a weight average molecular weight in a range of 15,000 to 40,000. |
