一些特种橡胶如氯丁橡胶、丁腈橡胶、丙烯酸酯橡胶、聚氨酯橡胶和氯化聚乙烯都需要使用增塑剂解决一些可能出现的问题。由于特种橡胶拥有更好的耐高温、耐油、耐溶剂、耐寒性能、老化性能和物理性能,所以尽管成本较高仍得到广泛应用。分子结构中的极性基团是拥有这些特性的原因。这些极性基团可改善橡胶的耐烃类溶剂和耐高温性能,同时也对低温性能产生了不利影响,如玻璃化转变温度(Tg)升高和聚合物发脆。使用
Some specialty rubbers such as neoprene, nitrile rubber, acrylate rubber, urethane rubber and chlorinated polyethylene require the use of plasticizers to solve some problems that may arise. As specialty rubber has better heat resistance, oil resistance, solvent resistance, cold resistance, aging properties and physical properties, it is widely used in spite of its high cost. Polar groups in the molecular structure are the reason for having these properties. These polar groups improve the hydrocarbon-resistant solvents and high-temperature properties of rubber while adversely affecting the low-temperature properties such as increased glass transition temperature (Tg) and brittleness of the polymer. use
