Abstract RU 2779982 C1

FIELD: polymers.

SUBSTANCE: invention relates to a cross-linked grafted or non-grafted polymer composition containing a cross-linked polymer containing hydrolysable silane groups. Proposed is a cross-linkable polymer composition for manufacturing cable insulation, cable or pipe sheathing, containing (A1) a cross-linkable non-grafted copolymer containing hydrolysable silane groups, (B) a condensation catalyst, and (C) a cross-linking accelerator, wherein the cross-linkable non-grafted copolymer containing hydrolysable silane groups (A1) is produced by copolymerising one or more olefin monomers with a non-saturated silane compound, wherein the non-saturated silane compound is represented by the formula R1SiR2qY3-q, where R1 constitutes an ethylene non-saturated hydrocarbyl, hydrocarbyloxy, or (meth)acryloxy hydrocarbyl group; R2 constitutes an aliphatic saturated hydrocarbyl group; Y, being the same or different, constitutes a hydrolysable organic group; and q constitutes 0, 1 or 2; where the cross-linking accelerator (C) includes a metal hydroxide, an alkali metal hydroxide, an alkaline earth metal hydroxide, or mixtures thereof; where the condensation catalyst (B) includes a metal carboxylate; and where the cross-linking accelerator (C) is present in an amount of 6 to 75% wt. as calculated for the entire cross-linkable polymer composition. Also proposed is a cross-linkable polymer composition based on the cross-linkable grafted copolymer containing hydrolysable silane groups, a cross-linked polymer composition, variants of products made thereof, and an application of the above cross-linking accelerators.

EFFECT: proposed compositions are better cross-linked at different temperatures when using a lower amount of Lewis acids as a silanol condensation catalyst.
