    • A novel class of silicon-containing vinyl polymers having in its molecule at least one constitutent unit of the formula ##STR1## wherein R.sup.1 is a substituted or unsubstituted monovalent hydrocarbon residue; R.sup.2 is ##STR2## R.sup.3 is hydrogen or methyl group; R.sup.4 is a substituent directly bonded to silicon atom and is selected from a substituted or unsubstituted alkylene, or a substituted or unsubstituted alkylene containing hetero atoms; m and n each is a positive integer, which will fulfill the requirement of 2.ltoreq.m+m.ltoreq.4; A is a direct bond, ##STR3## phenylene or substituted phenylene; B is ##STR4## R.sup.5 and R.sup.6 each represents an alkylene, providing that when A is ##STR5## m+n is 2. The present vinyl polymers are very useful in various technical fields including preparation of lens and other molding products, paints and various industrial resins.
    • 一类新颖的含硅乙烯基聚合物,其分子中具有至少一个下式的组成单元,其中R1是取代或未取代的一价烃残基; R2是氢或甲基; R4是与硅原子直接键合的取代基,其选自取代或未取代的亚烷基,或取代或未取代的含有杂原子的亚烷基; m和n分别为正整数,满足2 亚苯基或取代亚苯基; B是图像,R 5和R 6各自表示亚烷基,条件是当A为m + n为2.本发明的乙烯基聚合物在各种技术领域中非常有用,包括制备透镜和其它成型产品,油漆和各种 工业树脂。
