초록

Polyacrylamide (PAAm)는 내수성이 떨어지는 단점이 있기 때문에, 이의 개선을 위하여 가교가능한 반응성기 를 가진 ,N-methylolacrylamide (N-MA)와 공중합하였다. 중합속도(R_p)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.

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(R_p) was investigated by dilatometry, R_p was proportional to initiator, monomer concentrations and the ratio of comonomer, however, R_p 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.
