    摘要： It is provided a process for the preparation of a polymer from a vinyl halide monomer A and a monomer B whose homopolymer has a Tg lower than that of the polymer produced by polymerizing the vinyl halide monomer, wherein A wt %/B wt % in the polymer is from 99.7/0.3 to 40/60; the process comprising a) mixing water, an amphiphilic substance,from 10 to 100 wt % of the monomer B at an appropriate temperature, adding an initiator and allowing the system to react until reaching a conversion from 10 to 100 mol %, b) adding from 20 to 100 wt % of an amount ofmonomer A and the remaining amount of monomer B, and allowing the mixture to react until the conversion of the monomers reaches a value higher than 20 wt %, and c) adding the remaining amount of monomer A and allowing the system to react.

    摘要： The present invention relates to a composition comprising a polymer which comprises poly(lactic acid) and an additive which comprises dipentaerythritol, wherein the weight percentage of the polymer is from 80 to 99.5%, and the weight percentage of the additive is from 0.5 to 20%. It also relates to the use of dipentaerythritol as a nucleating agent for polymers comprising poly(lactic acid); to a process for the preparation of moulded article from the composition comprising the polymer which comprises poly(lactic acid) and an additive which comprises dipentaerythritol; and to an injection moulded article made therefrom.
