Description

Изобретение относитс к отверждающимс составам, которые после отверждени пригодны в качестве тканеэквивалентного материала.The invention relates to curable compositions which, after curing, are suitable as tissue equivalent materials.

Известен отверждающийс состав, содержащий ненасыщенный полиэфир,аминоэфир, напримердиметиламиноэтилметакрилат, инициатор и ускоритель.A curable composition is known comprising an unsaturated polyester, an amino ester, e.g. dimethylaminoethyl methacrylate, an initiator and an accelerator.

Однако известный отверждающийс состав не обеспечивает получени отвержденного материала со свойствами, наиболее соответствующими составу мышечной ткани .However, the known curable composition does not provide a cured material with properties that are most consistent with muscle composition.

Согласно изобретению предлагаетс вводить в состав сополимер формальдегида с диоксаланом, полиэтилен и смесь натриевых , калиевых и кальциевых солей серной и фосфорной кислот при следующем соотношении компонентов состава, мас.%:According to the invention, it is proposed to introduce into the composition a copolymer of formaldehyde with dioxalane, polyethylene and a mixture of sodium, potassium and calcium salts of sulfuric and phosphoric acids in the following ratio of composition components, wt.%:
