一种柔性聚合物颗粒及其制备方法
摘要：
本发明涉及一种柔性聚合物颗粒及其制备方法，由单体(A)和单体(B)共聚而成，单体(A)为一种或多种非水溶性不饱和二烯单体，单体(B)是至少一种通式结构为上图的化合物，通式中R为C1～C12烷基、C1～C12烷基芳基、C1～C12烷基醚或C1～C12烷基酯；单体(A)含量占单体(A)和单体(B)总质量百分比的60～90％；单体(B)含量占单体(A)和单体(B)总质量百分比的10～40％；有极好的变形性、柔韧性、弹性和稳定性，应用于油田近井调剖、深部调剖和深部液流转向剂，高温高盐油井堵水、聚合物驱/复合驱防窜、酸化暂堵、蒸汽吞吐或蒸汽驱深部防窜、堵漏或降滤失等领域。
摘要（英）：

The present invention relates to flexible polymer particle and the preparation method, polymerized by a monomer (A) and a monomer (B). The monomer (A) is one or more than one non-aqueous unsaturated diene monomers and the monomer (B) is at least one compound with the above general formula structure. In the formula, R is C1 to C12 alkyl, C1 to C12 alkyl and aryl, C1 to C12 alkyl aether or C1 to C12 alkyl ester; the content of the monomer (A) accounts for 60-90 percents of the total quality of the monomer (A) and the monomer (B), and the content of the monomer (B) accounts for 10-40 percents of the total quality of the monomer (A) and the monomer (B). The present invention with good deformation, flexibility, elasticity and stability is applied in the fields of oil near wellbore profile control, deep profile control and deep liquid steering agent, high-temperature and high-salinity oil well ponding, polymer flooding/compound flooding resistance, acidification and temporary ponding, steam taking and sending out, or steam deep flooding resistance, leakage blocking or fluid loss, etc.
