ONE POT SYNTHESIS OF UREA METHACRYLATES
The present invention relates to one-pot synthesis of polymerizable and non-cyclic urea (meth)acrylates, preferably mono(meth)acrylates, via in situ synthesis of urea alcohols or amines, followed by direct reaction with (meth)acrylate reactive diluents. Urea alcohols/amines are obtained from isocyan...

| Zusammenfassung: | The present invention relates to one-pot synthesis of polymerizable and non-cyclic urea (meth)acrylates, preferably mono(meth)acrylates, via in situ synthesis of urea alcohols or amines, followed by direct reaction with (meth)acrylate reactive diluents. Urea alcohols/amines are obtained from isocyanates and alcohols, amines or hydroxylamines. Subsequently, a reaction occurs with the (meth)acrylate reactive diluent, and urea (meth)acrylate is obtained directly as a solution in the reactive diluent or as a pure substance after removal of the reactive diluent. The objective of the present invention is to provide a new method for preparing novel (meth)acrylate-based monomers for (aqueous) emulsion polymers applied in coatings or adhesives.
본 발명은 우레아 알코올 또는 아민의 원위치 합성, 이어서 (메트)아크릴레이트 반응성 희석제와의 직접 반응을 통한 중합성 및 비-시클릭 우레아 (메트)아크릴레이트, 바람직하게는 모노(메트)아크릴레이트의 원-포트 합성에 관한 것이다. 우레아 알코올/아민은 이소시아네이트 및 알코올, 아민 또는 히드록시아민으로부터 수득된다. 이어서, (메트)아크릴레이트 반응성 희석제와의 반응이 일어나고, 우레아 (메트)아크릴레이트는 상기 반응성 희석제 중의 용액으로서, 또는 반응성 희석제의 제거 후에 순수한 물질로서 직접 수득된다. |
