Process for the partition of oligu00c8mero acid (MET) acrylic paint, the use of compounds as agents for the partition to partition of oligu00c8meros acid (MET) acrylic paint.Device for the production of acid (MET) acrylic paint and use of this device in the production of acid (MET) acrylic paint, the present invention relates to a process for the partition of oligomers of acrylic acid (MET) of structure I in R ~ 1 ~ is a hydrogen atom or alkyl group. The C ~ 1 ~ C ~ 10 ~ R ~ 2 ~ is a hydrogen atom or a methyl group, and N is an integer ranging between 1 and 200.Optionally, in this invention, the agent of partition the structure R ~ 3 ~ - Oh or structure (R ~ 4 ~) ~ 2 ~ - N - H, where R ~ 3 ~ is a hydrogen atom, a C1 - C12 alkyl group or a group C ~ x ~ H ~ 2 ~. ~ x ~ - Oh, where x is an integer within the range between 1 and 12, and R ~ 4 ~ is an atom of hidrog u00eanio alkyl group or a C ~ 1 ~ C ~ 12 ~, with the proviso that none of the groups R ~ 4 ~ is hydrogen atom.In the oligomers of acrylic acid (MET) are heated as a partition to a temperature of at least 50 C at a pressure of at least 1 bar.The present invention also relates to the use of water, optionally with a compound pru00f3tico as a partition of the oligomers of acrylic acid (MET), a device for the synthesis of acrylic acid (MET), the use of this device for production of acrylic acid (MET). As the acrylic acid (MET) produced using this device.
