Thermosetting resinous molding compositions

摘要

A thermosetting resinous composition characterized in constituting at least two oligomeric polyester segments terminally joined through a polyurethane residue and having end groups containing polymerizable unsaturation. Further disclosed are the thermoset products obtained by the addition polymerization of the aforesaid compositions in the presence or absence of a copolymerizable monomeric crosslinking agent. The resultant thermoset products are particularly useful in preparing molded articles.
