A process for preparing a trifluorovinylsilane represented by the general formula: (CF.sub.2 .dbd.CF).sub.n SiR.sub.4-n (I) where each R independently represents an alkyl group, an aryl group or an aralkyl group, and n is an integer of 1 to 4, which comprises the reaction of chlorotrifluoroethylene with a chlorosilane represented by the general formula: Cl.sub.n SiR.sub.4-n (II) where R and n are as defined above, in the presence of an alkyllithium. Also disclosed is a fluorine-containing polymer represented by the general formula: ##STR1## where each of x and m is an integer other than O, y is an integer including O, and each of R.sup.1, R.sup.2 and R.sup.3 is a lower alkyl group, an aryl group or an aralkyl group, which is prepared by polymerization of a trifluorovinyl silane (I) with active fluoride-ion generating catalyst.
一种制备三氟乙烯基硅烷的方法,该化合物的通式为:(CF.sub.2.dbd.CF).sub.n SiR.sub.4-n(I),其中每个R独立地表示烷基,芳基或芳基烷基,n是1至4的整数,包括以下步骤:在烷基锂的存在下,将氯三氟乙烯与通式为Cl.sub.n SiR.sub.4-n(II)的氯硅烷反应,其中R和n如上所述。还公开了一种含氟聚合物,其通式为:##STR1## 其中x和m分别是除O外的整数,y是包括O的整数,R.sup.1,R.sup.2和R.sup.3中的每一个都是较低的烷基,芳基或芳基烷基,该聚合物通过使用活性氟离子发生催化剂聚合三氟乙烯基硅烷(I)制备。
