Abstract
Abstract Subject invention relates to alk-1-enyl ether silicates having the formula [X].sub.4-n Si[OR.sub.1 OCH═CH--R.sub.2 ].sub.n wherein X is halogen or --OR wherein R is lower alkyl or a mixture of halogen and OR, a mixture of OR and hydrogen or a mixture of halogen and hydrogen; R 1 contains from 1 to 8 carbon atoms and is alkylene, alkenylene, alkynylene, optionally alkoxylated with up to 20 units of ##STR1## wherein Y is hydrogen or methyl and R 2 is each hydrogen or lower alkyl and n has a value of from 1 to 4. The invention also relates to the process for preparing the above vinyl ether silicates and to their use as chemically resistant coatings.
