Abstract
Abstract The invention relates to benzyloxy vinyl ethers having the structure ##STR1## wherein R 1 is lower alkyl; p is an integer having a value of from 0 to 2; q is an integer having a value of from 1 to 20; r is an integer having a value of from 1 to 6; n is an integer having a value of from 0 to 20; m is an integer having a value of from 0 to 1; Y is sulfur or oxygen; X is hydrogen or methyl and R and R 2 are each independently a radical having from 2 to 20 carbon atoms and are selected from the group of alkylene, arylene, aralkenylene and alkarylene optionally substituted with lower alkyl. The invention also relates to the process for preparing the above multifunctional benzyloxy vinyl ethers.

Claim 1
Independent Claim
118 words
The benzyloxy vinyl ether having the formula ##STR7## wherein R 1 is lower alkyl; p is an integer having a value of from 0 to 2; q is an integer having a value of from 1 to 20; r is an integer having a value of from 1 to 6; n is an integer having a value of from 0 to 20; m is an integer having a value of from 0 to 1; Y is sulfur or oxygen; X is hydrogen or methyl and R and R 2 are each independently a radical having from 2 to 20 carbon atoms and are selected from the group of alkylene, arylene, aralkenylene and alkarylene optionally substituted with lower alkyl.
Claim 2
Dependent Claim
118 words
The benzyloxy vinyl ether having the formula ##STR7## wherein R 1 is lower alkyl; p is an integer having a value of from 0 to 2; q is an integer having a value of from 1 to 20; r is an integer having a value of from 1 to 6; n is an integer having a value of from 0 to 20; m is an integer having a value of from 0 to 1; Y is sulfur or oxygen; X is hydrogen or methyl and R and R 2 are each independently a radical having from 2 to 20 carbon atoms and are selected from the group of alkylene, arylene, aralkenylene and alkarylene optionally substituted with lower alkyl.
Claim 3
Dependent Claim
37 words
The benzyloxy vinyl ether polymer of claim 1 wherein Y is oxygen; n has a value of from 0 to 5; q has a value of from 1 to 5 and r has a value of one.
Claim 4
Dependent Claim
78 words
The condensation process which comprises contacting a hydroxy vinyl ether reactant having the formula ##STR8## and a poly(benzyloxy) ether co-reactant having the formula ##STR9## in a mole ratio of between about 1:1 and about 20:1 based on --OH per oxirane or thiirane moiety, and reacting the resulting mixture under anhydrous conditions in the presence of a base catalyst at a temperature of between about 100° C. and about 200° C. to produce the corresponding product of claim 1.
Claim 5
Dependent Claim
29 words
