Multifunctional sulfur-containing polymers, compositions thereof and methods of use |
摘要 |
Disclosed are multifunctional sulfur-containing polymers that are the reaction products of a sulfur-containing diol, a polyol containing at least three hydroxyl groups per polyol molecule, and an aldehyde, a ketone, or a combination thereof. Sealant compositions comprising the multifunctional sulfur-containing polymers are also disclosed. |

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). |
