FIELD: polymer materials.
SUBSTANCE: invention provides granule containing matrix of star-shaped polyamide and fibers, which granule can be obtained when performing following steps. (a) At least one matrix of star-shaped polyamide in molten state is combined with fibers selected from group consisting of continuous fibers and fibers with lengths constituting 80% granule length and preferably at least 100% granule length. Matrix of star-shaped polyamide is obtained by copolymerization of mixture of monomers containing polyfunctional compound including at least three identical reactive functional groups such as amino groups and carboxylic acid groups, in particular monomers depicted by following general formulae: X-R2-Y (IIa) and/or 
(IIb), if needed, monomers of general formula Z-R2-Z (III), wherein Z represents functional group identical with reactive functional groups of polyfunctional compound; R1 and R2, the same or different, represent substituted or unsubstituted aliphatic, cycloaliphatic, or aromatic hydrocarbon radicals containing from 2 to 20 carbon atoms and optionally include heteroatoms such as nitrogen and oxygen atoms; Y represents primary amino group when X is carboxylic acid group or Y represents carboxylic acid group when X is amino group. (b) Composition obtained in step (a) is the molded into stick, which is cur into granules. Granules are used to prepare high-strength products.
EFFECT: increased strength of granules.
