This thermoset material can be used as an alternative to polyester and epoxy materials as the thermoset polymer matrix in composite materials where its characteristics strengths and bulk cost are intermediate between polyester and epoxy. Thus if a hard rigid thermoset is desired the divinyl ether concentration constitutes a higher percentage of the monomer mixture than in the case where a rubbery elastic thermoset resin is.

Vinylbenzyl ether terminated oligo 2 6 dimethyl 1 4 phenylene ether 1 has been commercialized by mitsubishi gas chemical in the name of ope 2st. They were first used after world war ii and. Epoxy vinyl ester resins ver are an important class of high performance thermoset molding resins. These resins form durable laminates and coatings.

A thermoset polymer matrix is a synthetic polymer reinforcement where polymers act as binder or matrix to secure in place incorporated particulates fibres or other reinforcements. Revised 1 october 1992 the divinyl ether of diallylbisphenol a veaba was investigated as a candidate for advanced composite matrix resin.

They were first developed for structural applications such as glass reinforced plastic radar domes on aircraft and graphite epoxy payload bay doors on the space shuttle. The elastomeric nature of these vinyl ether based fibers can be partly attributed to their subambient t gand partly to the cross link density monomer structure and resulting network homogeneity. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Vinyl monomers are used in unsaturated polyester glass fibre reinforced artificial marble and gelcoat.

Ope 1 is used in high frequency printed circuit board due to its low dielectric characteristic after curing. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. Resins for thermoset composites thermoset composites consist of a matrix the thermoset resin and reinforcements. Resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn.
