Polymer and polymeric composite materials have extensive application in the various fields. These light weight materials exhibit excellent mechanical properties, high corrosion resistance, dimensional stability and low cost. Traditionally, polymers and polymeric composites have been derived from petroleum, but it is being exhausted a fast rate. In the past few decades, natural and renewable resources have received a great amount of attention. Vegetable oils have received particular attention due to their abundance, high purity and especially their carboxyl and olefinic functionalities, which enable to take part in various chemicals reactions. Among those reactions, these epoxidation plays an important role. The product of this process - epoxidized vegetable oil are widely used in polymer chemistry. Those products are not only excellent plasticizers ofpoly(vinylchloride), efficient stabilizers and reactive diluents for paint industry, but also matrix resins for environmentally friendly artificia-stone. In this work, the curing process of the epoxidized linseed oil (ELO) by 4-methylhexahydrophthalic anhydride (MHHPA) in presence of 1-methylimidazole (NMI) catalyst has been investigated. The results showed that at temperature 120°C with the mole ratio ELO/MHHPA 0.96 in the presence of 1.5 wt percent NMI and 2.0 wt percent polyol-PT1 the cured resin has high hardness Barcol (51+52) and meet the requirements of the matrix resin for the manufacture of artificial stone.
