Abstract
Polyacrylamide(PAAm) have low resistance for water in many applications. For this reason, Coploymerization of AAm with N-methylolacrylamide (N-MA) that have crosslinkable reactive group was carried out. The rate of polymerization(Rp) was investigated by dilatometry, Rp was proportional to initiator, monomer concentrations and the ratio of comonomer, however, Rp was decreased at some integrated concentrations. The crosslinking characteristics were investigated by Torsional Braid Analysis (TBA) method, the rate of crosslinking was enhanced by using 5 mole% zinc nitrate and 2 mole% glycerin.

Polyacrylamide (PAAm)는 내수성이 떨어지는 단점이 있기 때문에, 이의 개선을 위하여 가교가능한 반응성기 를 가진 ,N-methylolacrylamide (N-MA)와 공중합하였다. 중합속도(Rp)를 dilatometry법을 이용하여 측정한 결과, 개시제와 단량체의 농도가 증가할수록 중합속도는 빨라졌으나 진한 농도에서는 오히려 느려졌다. 가교특성은 Torsional Braid Analysis (TBA)법으로 측정하였고 가교속도는 zinc nitrate와 글리세린을 각각 5 mole%와 2mole%로 하여 경화시켰을 때 가장 빨랐다.
