Modifizierte ungesättigte Polyester und Verfahren für ihre Herstellung. |
摘要 |
An unsaturated polyester modified by having an elastomeric polymer segment chemically bonded thereto, the chemical bond comprising a cyclic member containing six carbon atoms, and process for the preparation therefor by incorporating a conjugated diolefin group into an elastomeric polymer, reacting the conjugated diolefin group with an ethylenically unsaturated group in an unsaturated polyester so as to chemically combine the elastomeric polymer and the polyester through a cyclic hydrocarbon structure comprising 6 C atoms and recovering a modified unsaturated polyester. |
