Abstract
Abstract An aromatic vinyl ether of the formula: <CHEM> wherein: R1, R2, R4 , R5, R6, R8, R9 , and R10 are independently selected from hydrogen, halogen, and C1-C8 alkyl radicals; R3 and R7 are independently selected from C1-C8 alkylene radicals; and R11 and R12 are independently selected from allyl and methallyl. Also disclosed are various other aromatic vinyl ether compounds, chain-extended derivatives thereof, and liquid vinyl ether blends, and a method of making the aromatic vinyl ether compounds at high yield. The aromatic vinyl ether compounds, chain-extended vinyl derivatives, and/or liquid vinyl ether blends of the invention may be employed as vinyl ether components together with cationic photoinitiators, to provide cationically polymerizable vinyl ether compositions having utility in applications such as coatings, adhesives, and sealants.
