FIELD: chemical technology.
SUBSTANCE: invention relates to technology for making articles from thermoplastics, in particular, to compounds and compositions comprising specific metal salts and bicyclo[2.2.1]heptane dicarboxylates providing suitable high indices of articles made of polyolefins. Proposed salts and their derivatives are used as cross-linking agents and/or clearing agents for such polyolefins and provide the excellent crystallization point values, rigidity (density) and compatibility with calcium stearate in the end polyolefin. Also, proposed compound possess very low hygroscopicity and, therefore, the excellent stability in storing as powder-like or granulated compositions. Also, invention considers additive compositions prepared from polyolefins and methods for synthesis of polyolefin with such compounds.
EFFECT: improved and valuable properties of thermoplastics.
