VINYLCHLORID UND HETEROZYKLISCHE, THION FUNKTIONELLE POLYURETHAN POLYMERMISCHUNGEN UND IHRE VERWENDUNG IN MAGNETISCHEN AUFZEICHNUNGSTRAEGERN

摘要

The invention relates to a composition comprising: (a) about 5 to 95 weight percent of a vinyl chloride copolymer; and (b) about 5 to about 95 weight percent of a polymer selected from the group consisting of polyurethane and polyurethane urea, said polymer having at least one pendant heterocyclic group, wherein said polymer has a heterocyclic group equivalent weight of from about 500 to about 100,000, and wherein said heterocyclic group is derived from a compound selected from the group consisting of tautomers thereof, and mixtures thereof, wherein said heterocyclic group is formed by reacting said heterocyclic compound into said polymer; wherein said weight percentages are based upon the total weight of said composition.
