HYDROXYL POLYESTERS HAVING A MOLECULAR WEIGHT OF FROM ABOUT 300 TO ABOUT 20,000 ARE PREPARED BY POLYMERIZING A LACTONE HAVING FROM 7 TO 9 MEMBERS IN T HE RING IN THE PRESENCE OF A HYDRAZINE. THE POLYESTERS ARE SUITABLE FOR PLASTICIZERS AND STABILIZERS FOR POLYVINYL CHLORIDE OR AS A REACTANT WITH POLYISOCYANATE TO PREPARE POLYURETHANES.

Substrate with modified surface reactivity and stain resistance in biological reactions

本發明提供製備樣品槽表面之方法。在一些態樣中，製備樣品槽表面之方法涉及使該樣品槽與嵌段共聚物接觸以在該樣品槽之金屬氧化物表面上方形成抗污性覆蓋。在一些態樣中，提供鈍化及/或選擇性功能化樣品槽表面之方法。

PLUG-IN COPOLYMER USEFUL IN ELECTRODEPOSITION

Process for producing graft polymer

ABSTRACT OF THE DISCLOSURE A graft polymer wherein an iodine-containing fluororubber has been grafted on an ethylene-.alpha.-olefin copolymer can be obtained by mixing 30 parts by weight of an iodine-containing fluororubber (a vinylidene fluoride-hexafluoropropylene copolymer containing iodine) and 70 parts by weight of an ethylene-propylene copolymer rubber at 180°C for 30 minutes while applying shear deformation using a Brabender mixer.
