摘要:
Oil soluble rheology modifying star macromolecules having a core and five or more polymeric arms, and compositions comprising the same. The polymeric arms on a star are covalently attached to the core of the star; each polymeric arm comprises one or more (co)polymer segments; and at least one polymeric arm and/or at least one polymeric segment exhibits a different solubility from at least one other polymeric arm or one other polymeric segment, respectively, in a reference liquid of interest. The oil soluble rheology modifying star macromolecules and compositions comprising the same for use in oil based systems.
摘要:
Polyester based polycarbonate (meth)acrylates prepared by the reaction of a alkylene or arylene diol polycarbonate with an anhydride or its dicarboxylic acid to form a carboxyl terminated diester, reacting the diester with a diglycidyl ether and an acrylic or methacrylic acid to form an acrylate terminate polymer which is useful for radiation cured coatings which have superior adhesion and reverse impact strength when applied to plastic substrates.
