Abstract
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.
Claims6
A sulfur-containing polymer comprising the reaction products of reactants comprising:
- (a) a sulfur-containing diol, wherein the sulfur-containing diol is a thioether diol;
- (b) a polyol containing at least three hydroxyl groups per polyol molecule;
- and
- (c) a reactant selected from an aldehyde, a ketone, and a combination thereof.
A sulfur-containing polymer having the structure 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 independently C2-6 alkanediyl;
- each R3 is independently selected from hydrogen, C1-6 alkyl, C7-12 phenylalkyl, substituted C7-12 phenylalkyl, C6-12 cycloalkylalkyl, substituted C6-12 cycloalkylalkyl, C3-12 cycloalkyl, substituted C3-12 cycloalkyl, C6-12 aryl, and substituted C6-12 aryl;
- and
- Z represents the core of an m-valent parent polyol Z(OH)m.
A sulfur-containing polymer comprising the reaction products of reactants comprising:
