Abstract:
The invention relates to a method for producing aqueous polymer dispersions containing colorants by radical aqueous emulsion polymerisation of ethylenically unsaturated monomers in the presence of radical-forming initiators. At least a proportion of the monomers is used in the form of an oil-in-water emulsion E1 whose disperse phase contains at least one oil-soluble colorant. The inventive method is characterised in that the disperse phase of E1 is essentially made up of colorant-containing monomer droplets with a diameter

Abstract:
Production of polymethylenamine (I) uses an educt comprising an optionally substituted imidazol(in)e or 1,3,2-diazasilacyclo-pentene or -pentadiene compound (II); and involves free radical polymerization of (II), using a free radical initiator with a half life of 5-30 minutes at the selected reaction temperature and hydrolysis of the resultant polymer if necessary. Production of polymethylenamine (I) uses an educt comprising an optionally substituted imidazol(in)e or 1,3,2-diazasilacyclo-pentene or -pentadiene compound of formula (II); and involves free radical polymerization of (II), using a free radical initiator with a half life of 5-30 minutes at the selected reaction temperature and hydrolysis of the resultant polymer if necessary: [Image] Q : C or Si, with the broken line indicating an optional double bond; R1>, R2>H, R, formyl; (un)saturated, linear or branched, optionally aryl-substituted aliphatic 1-40 C acyl, R', R5>OCO(O), -C(O)NR6>R7> or -C(O)XR8>; R : (un)saturated, linear or branched, optionally aryl-substituted 1-40 C alkyl or optionally alkyl-substituted 5-6 C aryl; R' : optionally alkyl-substituted aromatic 5-6 C acyl; R5>R; R6>, R7>H, R or R'; X : O or S; R8>H or R; R3>, R4>H, R, OR or OH or together =O or =S.
