摘要： Polymeric materials which comprise a hydroxyalkyl ester of acrylic acid or methacrylic acid, a monoethylenically .alpha.,.beta.-unsaturated carboxylic acid, and an alkyl ester or esters of acrylic and/or methacrylic acid are partially neutralized, isolated, and powdered to give useful powder coating compositions. The composition may be utilized for coating metallic articles.

摘要： Disclosed is a polymer and its preparation by reacting part of the monomers in the reactor in such a way as to obtain a high molecular weight product, and reacting at least one other portion of the monomer in the same reactor in such a way as to obtain at least one low molecular weight fraction. The products are useful in contact adhesives, particularly when blended with an aminoplast or phenoplast as a tackifier and crosslinker, and with a thickening agent such as polyvinyl alcohol.
