ABSTRACT:
Reactive monomers are prepared by reacting (1) an aromatic compound containing a polymerizable ethylenically unsaturated group and a group containing a hydrogen atom reactive with an NCO or NCS group, (2) a compound having at least one oxyalkylene group and at least one group containing at least one hydrogen atom reactive with an NCO or an NCS group and (3) a compound having an average of more than one NCO and/or NCS groups per molecule. These reactive monomers are useful as reactive modifiers for polyester and vinyl ester resins.
