EXTRUDABLE SELF-ADHERING ADHESIVE COMPOSITION AND METHODS OF OBTAINING THEREOF

摘要

FIELD: chemistry.SUBSTANCE: invention relates to a polymer composition with separate phases for the application as a self-adhering adhesive material and versions of methods for the said composition obtaining. The polymer composition with separate phases contains the first phase - polyurethane domains, with polyurethane being formed in the presence of butyl rubber by the interaction of isocyanate with phenolic resin; and the second phase - butyl rubber matrix. The composition contains at least 35 wt % of butyl rubber relative to the total weight of the composition and is extrudable.EFFECT: obtaining the compositions for self-adhering adhesive tapes which can be subjected to secondary processing.10 cl, 1 tbl, 2 dwg, 10 ex
