Abstract: The process of heating a resin composition which exhibits reversible crosslinking behavior prepared by copolymerizing an alpha, beta ethylenically unsaturated monomer with an oil soluble metal salt prepared by reacting (A) a metal compound with (B) an acid functional compound which is a reaction product of (1) an alpha-beta ethylenically unsaturated hydroxy compound and (2) a carboxylic polyacid, anhydride, sulfur oxide, or phosphorus oxide so as to cause reversible crosslinking is disclosed.

Abstract: A polyolefin composition comprising a discontinuous polymer phase dispersed in a continuous polyolefin phase is disclosed. The discontinuous polymer is polymerized by a method comprising reacting a blend or mixture of the polyolefin and one or more polyethylenically unsaturated monomers in the presence of a free radical initiator. Articles and materials made from he composition exhibit several advantageous properties as compared to the corresponding unmodified polyolefins, for example printability, paintability, and dyeability in the case of spun fiber, sheets, automotive applications such as interior parts and bumpers; toughness and abrasion resistance in the case of flooring, and impact strength in the case of siding.

Abstract: A composition comprising a polymer according to Structure 1 wherein R is H, Me, Et or C6H5; R? is H or Me; n is a number from 1 to 100; and Z is a number from 1 to 3; f is a number from 1 to 5, with f=1 if B is nothing; A is residue of a hydrogenated polybutadiene backbone; and B nothing or it is a difunctional organic linking group is disclosed.
