摘要

Process for the production of acid (MET) acrylic paint device for the production of acid acrylic paint, their use in the production of acid (MET) acrylic paint, acrylic paint, polu00ecmeros acid (MET) absorbing water, and fibers, sheets, foams and composites.The present invention relates to a process for the production of acrylic acid (MET), by which the acid (MET) acrylic acid is produced and its (MET) acrylic is then preferably raw and continuously purified, in which the acid (MET) acrylic purification comprises the SEC continues Uintes stages: (a) a composition comprising (MET) acrylic and impurities.The impurities are precipitated in crystalline form from the composition; (b) the crystal precipitated impurities from the composition are separated.The invention also relates to acrylic acid (MET) obtained by this process, a device for production of acrylic acid polymers (MET), absorbing water, acrylic acid (MET), the use of water absorbing polymers, as well as fibers, sheets, foams and composites.
