Carboxylic acid-modified vinylic polymeric compositions

Abstract

This invention relates to novel carboxylic acid-modified vinylic polymeric compositions and the process for preparing them. In particular, the invention relates to novel carboxylic acid-modified vinylic polymeric compositions which exhibit properties that make them useful as support resins for producing polymer latices which can be employed in the formulation of various water-based coatings and inks, particularly flexographic inks. More particularly, these carboxylic acid-modified vinylic polymeric compositions are produced by the addition polymerization reaction of vinylic monomers in the presence of dimer acids, trimer acids, dimerized rosins, or mixtures thereof.

Description

technical field

[0001] The present invention refers to a novel carboxylic acid modified vinyl polymer composition and its preparation method, especially the properties exhibited by it can be used as an auxiliary resin for the production of polymer latex carboxylic acid modified vinyl polymer composition, As a result, these latexes can be used to prepare various water-based coatings and inks, especially offset printing inks. Specifically, these carboxylic acid modified vinyl polymer compositions are prepared by addition polymerization of vinyl monomers in the presence of dimer acid, trimer acid, dimerized rosin, or mixtures thereof. Background technique

[0002] Inks and overprint formulations used in a variety of printing applications are in high demand for certain high performance characteristics. Since typical surfactant-based emulsion polymerization products do not have the desired rheological properties for these applications, it is often necessary to add auxiliary resi...
