主权项 1. A terminal-modified sulfur-containing polymer comprising the reaction products of reactants comprising: (a) a sulfur-containing polymer of Formula (I); wherein: each n is an integer selected from 1 to 50;m is an integer selected from 3 to 6;each p is 1;each R1 is C2-6 alkanediyl;each R3 is hydrogen; andZ represents the core of an m-valent parent polyol Z(OH)m; and (b) a compound comprising: (i) a terminal isocyanate group, a terminal epoxy group, a terminal vinyl group, a terminal thiol group or a terminal amine group; and(ii) a group that is reactive with the hydroxyl groups of the sulfur-containing polymer of Formula (I).
