METHOD OF PREPARING ELASTOMERIC MIXTURE, ELASTOMERIC MIXTURE FOR MAKING ARTICLES AND ARTICLE

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of preparing an elastomeric mixture and to substances for enhancing processing properties when using elastomeric mixtures in articles. The method of preparing an elastomeric mixture involves bringing an isobutylene-based elastomer into contact with processing property enhancing substance which contains a functionalised polymer, having at least one halogen group and having molecular weight Mn between 450 and 5000. The elastomeric mixture is used to make articles such as the inner lining tubeless tyres. ^ EFFECT: invention improves the method of preparing elastomeric mixtures and articles from said mixtures with low air permeability and retention of physical properties. ^ 18 cl, 8 tbl
