摘要
研究了在不同单体质量分数(ω(单体))范围(25％～50％和10％～26％)丙烯酰胺(AM)、丙烯酰胺/丙烯酸钠(AM/SA)和丙烯酰胺/(2-甲基丙烯酰氧乙基)三甲基氯化铵(AM/DMMC)反相微胶乳的相对分子质量。较高ω(单体)范围内,(AM)∝ω(AM)^(0.92),(AM/SA)∝ω(AM/SA)^(0.68),(AM/DMMC)∝ω(AM/DMMC)^(2.05);较低ω(单体)范围内,(AM)∝ω(AM)^(0.57),(AM/SA)∝ω(AM/SA)^(0.58)和(AM/DMMC)∝ω(AM/DMMC)^(1.26)。不同ω(单体)范围内M_v对ω(单体)的反应级数不同的原因可能是在不同ω(单体)范围内单体水溶液的粘度对反相微胶乳M_v的影响程度不同。
The relative molecular masses of inverse microlatexes polymerized in acrylamide(AM). acrylamide-so-dium acrylate(AM-SA)and acrylamide-(2-methacryloyloxyethyl) trimethyl ammonium chloride(AM-DMMC) inverse microemulsion at different monomer mass fraction ranges are studied. Mv ∝ w( AM)0.92, Mv ∝ w ( AM-SA)0.68,Mv ∝w(AM-DMMC)2.05at higher monomer mass fraction range(25%-50%)while Mv ∝ w (AM)0.57,Mv∝ w(AM-SA)0.58 .Mv ∝w(AM-DMMC)1.26 at lower monomer mass fraction range (10%-26%). The reason for the different orders with respect to w(monomer)for Mv at different monomer mass fraction ranges is discussed.
