膠凝劑的分子結(jié)構(gòu)設(shè)計(jì)應(yīng)考慮具有較好的抗溫抗鹽性能,膠凝劑的分子結(jié)構(gòu)設(shè)計(jì)具體依據(jù)以下六個(gè)方面:
⑴ 在分子鏈上引入可增加剛性的結(jié)構(gòu),選用碳鏈高分子和在分子中引入可增加分子鏈剛性的環(huán)狀結(jié)構(gòu),可使聚合物的熱穩(wěn)定性明顯提高;
⑵ 在分子上引入大側(cè)基或剛性側(cè)基,可使聚合物具有較高的熱穩(wěn)定性。因剛性側(cè)基的位阻效應(yīng),分子運(yùn)動(dòng)阻力大,聚合物溶液的表觀粘度降低幅度較?。?br /> ⑶ 聚合物引入可抑制酰胺基水解的單體,可以抵消因分子鏈上酰胺基的水解抗溫耐鹽性能降低的缺點(diǎn),可使聚合物的抗溫耐鹽性能大幅度提高;
⑷ 疏水基團(tuán)的水溶性聚合物具有鹽增粘效應(yīng),因此,在聚合物合成中引入疏水基團(tuán)是改善聚合物耐溫抗鹽性的有效途徑;
⑸ 聚合物中最好引入含有耐水解基團(tuán),來增加產(chǎn)物的耐鹽性能。改性的丙烯酰胺類膠凝劑比較合適,因此采用耐水解的單體與 AM 等單體共聚可以獲得耐溫抗鹽性能優(yōu)良的水溶性聚合物;
⑹ 還可以在分子中引入對(duì)鹽不敏感的基團(tuán)來提高分子的耐鹽性[3]。
