Abstract
A dendritic macromolecule having the following characteristics (i) an active hydrogen content of a least 3.8 mmoles/g and (ii) an active hydrogen functionality of at least 16 and which macromolecule is mixable at a ratio of at least 15% by weight with a polyether polyol having a hydroxyl value of at most 40 mg KOH/g to form a stable liquid at 23.degree. C. The subject dendritic macromolecule confer significant load building properties to isocyanate based foams and elastomers such as polyurethane foams and elastomers and may be used for this purpose to partially or fully displace current relatively expensive chemical systems which are used to confer load building characteristics to such foams and elastomers.
