反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The procedure of D(1) above was repeated except that 0.75 gram of ethylene diacrylate was used in place of the allyl acrylate, and the amount of maleic anhydride was increased to 30 grams. Yield: 417 grams. The branched tetrapolymer had about 50 mole percent of ethylene units, the units being arranged -(E)-(B')-, as in D(2). The weight percent of maleic anhydride was 3.9.

实验步骤: 2-Methylaziridine (9.1 gm) was charged in a 100 ml round bottle reaction vessel equipped with a condenser and dropping funnel. Ethylene glycol diacrylate (13.5 gm) was slowly added to the solution while stirring with a magnetic stirrer to maintain the solution temperature below about 40°-45° C. The resulting solution was further stirred at 50° C. for 30 minutes and at room temperature for 30 minutes. Ethylene glycol di(2-methyl-1-aziridinepropionate) was formed as a slightly yellowish viscous liquid and used without further purification. Trimethylolpropane tris[3-(2-methyl-1-aziridinyl)propionate] was also prepared by adding trimeylolpropane triacrylate (9.87 gm) to 2-methylaziridine (5.7 gm) using the foregoing method. equipped with a condenser to maintain the solution temperature below about 40°-45° C The resulting solution was further stirred at 50° C. for 30 minutes and at room temperature for 30 minutes

实验步骤: The procedure of D(1) above, was repeated except that 1.2 grams of ethylene diacrylate were used in place of the allyl acrylate. Yield: 479 grams. The branched tetrapolymer obtained had about 50 mole percent of ethylene units. The polymer chain consisted principally of units -(E)-(B')-, where E is ethylene and B' is randomly selected from ethyl acrylate, ethylene diacrylate, and maleic anhydride (3.8 weight percent). The branched tetrapolymer obtained

实验步骤: 50 Grams of N,N-diethylaminoethyl methacrylate, 50 g. of methyl methacrylate, 1 g. of Dupanol ME, 1 g. of Emulphor ON-870, 6 g. of ethylene diacrylate, 1 g. of potassium persulfate, and 0.5 g. of sodium bisulfite are dissolved or mixed with 1,000 g. of water. This mixture is tumbled in a water bath at 60° C. for 24 hr. to obtain a crosslinked copolymer of methyl methacrylate and N,N-diethylaminoethyl acrylate. The crosslinked polymer is separated from the aqueous dispersion by the method described in Example 4. mixed with 1,000 g
