Caprolactam → HCID 178516026, compound

Participants

Reaction Steps

In a second flask a 0.23 molar bromomagnesium caprolactam solution was prepared by adding 15 ml of a 3 molar ethyl magnesium bromide in diethyl ether solution to 200 gms dry caprolactam. Then 2.12 ml (2.0 gm) of a polyoxypropylene diamine (approximate m.w. 230) was added. The equivalents of primary and secondary amines of the polyfunctional amine were 30 percent of the acyl lactam group equivalent of the acyl lactam functionalized material. The material of the two flasks were injected into a mold as described above for Example 1. After 5 minutes, the casting was removed from the mold to give a nylon block copolymer containing 40% polyether.
