Halogenated polyphosphate polyol and prepolymer and preparation method therefor, as well as polyurea elastomer composition and polyurea elastomer and application

Abstract

Described are a halogenated hydroxyl terminated polyphosphoester and a prepolymer and a preparation method therefor, as well as a polyurea elastomer composition and a polyurea elastomer and an application. A structural unit of the halogenated hydroxyl terminated polyphosphoester contains a halogenated phenyl phosphate group structure and one or more linking groups; the halogenated phenyl phosphate group has a structure represented by formula (1), and the linking group has a structure represented by formula (2); n is 1-10; R1 is one or more of a substituted or unsubstituted benzene ring, —C(O)—R2—C(O)—, and substituted or unsubstituted alkenylene; R2 is selected from one or more of substituted or unsubstituted C1-C9 linear or branched alkylene, a substituted or unsubstituted benzene ring, and substituted or unsubstituted alkenylene; and X1, X2, X3, X4, and X5 are the same or different, are each H and/or halogen, and are not H at the same time;
