Abstract

The crosslinking density of polymer can be quantitatively calculated by the Flory-Rehner equation using the swelling experimental data and the lattice constant ${\beta}_1$ of interaction parameter (${\chi}$) in this equation should be chosen have used cautiously. This ${\beta}_1$ is the experimental data by rule of thumb, and researchers have used little different values respectively. Generally, the average molecular weight between crosslink points $M_c$ in the Flory-Rehner equation and the Mooney-Rivlin equation have the same value, and ${\beta}_1$ can be calculated when the $M_c$ in the Flory-Rehner equation is given. Therefore, in this research, firstly we calculated the $M_c$ using the selected ${\beta}_1$ (=0.34) and the swelling experimental data of 1,2,3-triazole polymer from the Flory-Rehner equation, secondly the $M_c$ from the Mooney-Rivlin equation is calculated by the tensile experimental data, and finally two $M_c$ were compared. As a result, two $M_c$ values were almost the same, and it was proved that the ${\beta}_1$ (=0.34) was selected properly.

폴리머의 가교밀도는 팽윤 실험 데이터를 이용한 Flory-Rehner 식에 의하여 정량적으로 계산할 수 있는데, Flory-Rehner 식에서 상호계수 (${\chi}$) 항에 있는 lattice constant ${\beta}_1$ 값은 주의해서 선정되어야 한다. 이 ${\beta}_1$ 값은 경험에 의한 실험값으로 연구자에 따라 조금씩 다른 값이 선택되어 사용되고 있다. 일반적으로 Mooney-Rivlin 식에서 가교점 사이의 평균 분자량 $M_c$ 값은 Flory-Rehner 식에서의 $M_c$ 값과 동일한 의미를 가지며 Mooney-Rivlin 식으로부터 $M_c$ 값을 구하면 Flory-Rehner 식에서 ${\beta}_1$ 값을 구할 수 있다. 따라서 본 연구에서는 먼저 Flory-Rehner 식의 상호계수 (${\chi}$) 항의 ${\beta}_1$ (=0.34) 과 1,2,3-트리아졸 폴리머의 팽윤 실험 데이터를 적용하여 $M_c$ 값을 계산하고, 두 번째로 인장 실험 데이터를 이용한 Mooney-Rivlin 식을 이용하여 $M_c$ 값을 계산 후 비교하였다. 결과적으로 두 개의 $M_c$ 값이 거의 유사하여 Flory-Rehner 식의 상호계수 (${\chi}$) 를 위해 선정한 ${\beta}_1$ (=0.34) 값이 적절함을 증명하였다.
