FIELD: chemistry.
SUBSTANCE: invention relates to a polymer dispersion which does not contain water and a volatile organic solvent, meant for preparing lubricant compositions for glass fibre and glasing glass fibre and structures from such fibres, particularly nets and fabric. The disclosed dispersion contains a product of polymerisation of at least one vinyl monomer in the presence of a radical initiator in a dispersion organic reaction medium represented by siloxanes, having at least one epoxy group in the terminal position. The dispersion contains 20-70 wt % polymer in form of fine, essentially spherical particles with size less than 40 mcm.The invention also discloses a method of preparing the dispersion, lubricating and glasing compositions, as well as glass fibre coated with said compositions.
EFFECT: dispersion has high polymer content and is stable in usual storage conditions.
