"Process in order to increase the speed of crystallization of copolu00ecmeros biodegradable poliidroxialcanoato,Process for the formation of an article molded from a poliidroxialcanoato biodegradable, as well as the molded article thus obtained.This is a process to increase the speed of crystallization of a first poliidroxialcanoato biodegradable comprising a copolymer or a mixture thereof,At least two monomeric units of randomised repetition (rrmu), with the first unit has the following structure: (I) in which R ^ 1 ^ is h, C1 or C2 alkyl alkyl.N is 1 or 2, and the second rrmu is different from the first rrmu and comprises at least one monomer selected from the group of structures (II) in which R ^ 2 ^ is a C3 - C19 alkyl or C3 - C19 alquenila,And (III) in which m is 2 to about 16, and the copolymer has a melting point TM1.By mixing in solution or by mixing in the fusion of the first poliidroxialcanoato biodegradable with (b) a second homopolymer or copolymer of poliidroxialcanoato biodegradable products QThe EU includes at least one monomer unit of randomised repetition has the following structure (IV): in which R ^ 3 ^ is h, C1 or C2 alkyl alkyl, and Q is 1 or 2.The second poliidroxialcanoato biodegradable has a melting point TM2, and TM2 is at least approximately 20 198 C higher than TM1.Are also presented the processes for the formation of articles molded from the mixture of the components (a) and (b).
