FIELD: chemistry.
SUBSTANCE: articles are obtained by preparing an initial mixture from 0.1-1.2 mm quartz granules and a polyether curable resin. The mixture is put onto a temporary substrate or a mould with dimensions of the end article. Further, the mixture undergoes vacuum compression with simultaneous vibration, after which the polyether resin is cured. The resin does not contain a reactive solvent and is formed from a reaction between at least one epoxidated triglyceride and at least one carboxylic anhydride in the presence of a catalytic initiator at 80-180°C.
EFFECT: invention enables to obtain slabs or blocks using Bretonstone technology with good mechanical and physical characteristics and absence of yellowing under the effect of UV radiation for 500 hours.
