    摘要： THIS INVENTION RELATED TO THE INTERPOLYMERIZATION OF OLEFINICALLY-UNSATURATED HYDROCARBONS BY MEANS OF ZIEGLER CATALYSTS. MORE PARTICULARLY, THIS INVENTIN RELATES TO A METHOD OF PREPARING NON-RUBBERY INTERPOLYMERS OF A MONOOLEFIN MONMER HAVING A SINGLE COPLYMERIZABLE ETHYLENIC GROUP, SAID INTERPOLYMER HAVING AN ESSENTIALLY SATURATED CARBON ATOM IN THE POLYMER MOLECULE AND CONTAINING SUFFICIENT ETHYLENICALLY-UNSATURATED GROUPS IN THE POLYMER MOLECULE TO PERMIT SUBSTANTIAL CURING OF FILMS THEREOF BY OXIDATIVE MECHANISM, EMPLOYING A ZIEGLER CATALYST IN A BATCH PROCESS IN WHICH THE CATALYST IS INCREMENTALLY ADDED.

    摘要： This invention relates to acryloxy(or methacryloxy)alkyl(or alkyloxyalkyl) acryloxy(or methacryloxy)hydroxyalkyl organic polycarboxylic esters prepared by reacting an organic acid anhydride selected from the group consisting of trimellitic anhydride and pyromellitic anhydride with a hydroxyalkyl acrylate or methacrylate and then reacting this half-ester with a glycidyl acrylate or methacrylate. These compounds are useful in coating compositions and particularly coating compositions curable by radiation.
