摘要:
The invention is concerned with an isocyanate-reactive composition comprising a polymer having a molecular weight of at least 500 containing a plurality of groups of the formula: ##STR1## wherein R.sup.1 represents hydrogen or a hydrocarbon radical;R.sup.2 represents a hydrocarbon radical;R.sup.3 represents an organic radical carrying at least one isocyanate-reactive group, andR.sup.4 represents hydrogen or an optionally substituted hydrocarbon radical. Such compositions are useful for making moulded elastomers and flexible foams.

摘要:
The instant invention relates to a process which comprises modifying a conventional polyoxyalkylene polyol by capping all the hydroxyl groups of the polyol with benzyl, aryl, substituted benzyl, substituted aryl or alkyl groups having 1 to 4 carbon atoms. This process comprises reacting the conventional polyoxyalkylene polyol with an alkali metal methoxide followed by reaction with an alkali metal hydride which in turn is followed by reaction with an organic halide.
摘要:
New surface-active phosphonic acid esters, which are inter alia suitable as emulsifiers and dispersants, a process for their preparation and emulsions and dispersions of water soluble polymers containing the new phosphonic acid esters and having high stability on storage.
摘要:
Highly functional, substantially linear, polyamines are prepared by reacting a primary amine with an epihalohydrin oligomer or a mixture of an epihalohydrin oligomer and a halohydrin-terminated derivative of a polyol. Displacement of the haloalkyl halogen groups of the polyamine with amine groups provides highly functional amine intermediates which are useful in the preparation of drainage aids and the like.
