    摘要： 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.

    摘要： The present invention provides a process for producing a variety of unsaturated carbamic acid derivatives from corresponding unsaturated carbamates by substitution reaction. The present invention provides a process for producing unsaturated carbamic acid derivatives, comprising reacting an unsaturated carbamate represented by ##STR1## wherein R represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, R.sup.1 represents a residue of an alcohol from which an OH group is removed,with an alcohol, a primary or secondary amine or an oxime at a temperature of 80.degree. to 150.degree. C. to substitute the --OR.sup.1 group in the formula (A).

    摘要： Quaternary ammonium salts having a 2, 3, 5, 6-tetrahydroxazolo [2, 3-b] oxazole nucleus, such as 4-aralkyl or alkyl-2, 3, 5, 6-tetrahydroxazolo [2, 3-b] oxazolium salts are disclosed. These quarternary ammonium salts are useful a cationic polymerization initiator or proton-donating catalyst of the heat latent type to be incorporated heat-curable coating and other resinous compositions.
