    Description / Table of Contents: Acrylamide (1) and p-nitrophenyl acrylate (2) can be copolymerized in any relative molar proportion by using azoisobutyronitrile as initiator and dimethylsulphoxide as solvent. Under different reaction conditions the degree of polymerization was found between 200 and 500. At the early stage of polymerization 2 is more frequently incorporated in the copolymers than 1. The copolymers are highly soluble in dimethylsulphoxide and react very easily with aliphatic or aromatic primary amines. Treatment of a copolymer with dry ammonia gas yields the corresponding polyacrylamide within a few minutes.
    Notes: Acrylamid (1) und p-Nitrophenylacrylat (2) lassen sich mit Azoisobuttersäuredinitril in Dimethylsulfoxid in jedem molaren Verhältnis polymerisieren. Je nach Reaktionsbedingungen entstehen Copolymere, deren mittlerer Polymerisationsgrad zwischen 200 und 500 liegt. Dabei wird 2 zu Beginn der Polymerisation etwas bevorzugt eingebaut. Die Copolymeren sind in Dimethylsulfoxid sehr gut löslich und zeichnen sich durch ihre hervorragende Reaktivität gegenüber primären aliphatischen und aromatischen Aminen aus. So werden sie durch Behandlung mit trockenem Ammoniak in wenigen Minuten glatt in die entsprechenden Polyacrylamide überführt.
