Abstract: In this paper, Central Composite Design（CCD）, a kind of response surface methodology, was used to explore the effects of pressure, reaction temperature, reaction time, amount of catalyst on the molecular weight of polylactic acid（PLA）formed by ring-opening polymerization of lactide. Based on the regression analysis, regression equations related to response values and factors were established. The residual normal probability map was evenly distributed in a straight line,and the credibility was 99... More
