Abstract
This invention relates to novel macromers prepared from amine based polyols, preformed stabilizers prepared from these macromers, and to polymer polyols prepared from the preformed stabilizers. The present invention also relates to processes for preparing these compositions.
Claims26
An ethylenically unsaturated macromer comprising the reaction product of:
- (a) an amine initiated polyether polyol having a hydroxyl functionality of 3 to 8, having a number average molecular weight of from 4000 to 15,000, and which comprises the reaction product of
- (i) an amine compound having an amine functionality of from 1 to 6 and a number average molecular weight of from 60 to 1000, wherein said amine groups are selected from primary and/or secondary amine groups, and optionally from tertiary amine groups, with the proviso that one or more primary and/or secondary amine groups is also present;
- with
- (ii) an alkylene oxide;
- with
- (b) an ethylenically unsaturated compound which is present in an amount such there is at least 0.08 mole unsaturation/mole polyol present in the resultant macromer;
- optionally, in the presence of
