FIELD: chemistry.
SUBSTANCE: invention relates to a liquid photopolymerizable composition (FPC) for laser stereolithography. Composition contains 96–98 wt% mixture of di(meth)-acrylic oligomers and (meth)acrylic monomer and 2–4 wt% photoinitiator of 2,2'-dimethoxy-2-phenylacetophenone. Said mixture contains 16–33 wt% di(meth)acrylic oligoether, 16–33 wt% (meth)acrylic (phenyl)ether monomer, 16–33 wt% di(meth)acrylic oligoglycol, 16–33 wt% di(meth)acrylate oligourethane, the formulas of which are given in the description.
EFFECT: proposed FPC has storage stability, good fluidity and enables to obtain three-dimensional models with high physical and mechanical properties.
