Title: ALTERNATIVE REACTIVE MONOMER CHEMISTRIES IN RESINS FOR PULTRUSION PROCESSING
Abstract: Vinyl toluene (VT), under the family of methyl styrenes, is a reactive monomer that embodies alternative molecular chemistry to traditional styrene monomer. While present in the market for a substantial period of time, this family of monomers has not been widely utilized in reactive polymer resins or low-profile resins (LP) supplied into pultrusion applications. Recent restrictive changes in ground level ozone non-attainment criteria, workplace exposure concerns and toxicity classification of styrene monomer (SM), coupled with the entry of additional vinyl toluene producers into the market, should present new incentives and opportunities for resin producers to supply products utilizing this alternate styrene free technology into the pultrusion market. This paper will provide comparative results focused on process efficiency and pultruded product properties obtained utilizing isopolyester resin in alternate monomer, vinyl toluene, versus the same properties obtained utilizing commercial isopolyester in styrene monomer. The paper will further investigate the properties obtained when only the low-profile resin utilizes alternate monomer, vinyl toluene.
