Abstract: The present invention relates to reaction products formed from maleic anhydride and amino carboxylic acids. The reaction products are particularly useful for grafting polyolefins to increase their polarity and therefore enhance their physical properties.

Abstract: A grafted polyolefin polymers having high polarity produced by grafting bi-functional N-substituted diacids to maleated or other functional group grafted polyolefin. The new polymers exhibit improved water miscibility, compatability and good adhesion to polar materials such as nylon, polyester, glass, and metal substrates.

Abstract: The present invention provides water-borne adhesives and adhesive emulsions comprising: (1) 25 to 55 weight percent of a grafted polyolefin comprising the reaction product of (i) a polyolefin, (ii) an ethylenically unsaturated monomer having functionality capable of reacting with an amino group and (iii) an amino carboxylic acid; (2) a minor amount up to 10 weight percent of a surfactant; and (3) 55 to 80 weight percent water.

Abstract: A method is provided to prepare a cationic transition metal catalyst, the method including the steps of: providing a disubstituted phosphine selected from the group consisting of RPH and R.sub.1 R.sub.2 PH wherein R is a divalent group selected from substituted and nonsubstituted hydrocarbon groups, R.sub.1 and R.sub.2 are independently selected from substituted and nonsubstituted hydrocarbon groups; combining the disubstituted phosphine with a salt of the formula R.sub.3 X.sub.n wherein X is a good leaving group and is a weakly coordinating anion and R.sub.3 is a substituted or nonsubstituted aliphatic hydrocarbon and n is 1, 2, or 3 to form a phosphonium salt of a formula selected from R.sub.3 (RP.sup.+ H).sub.n nX.sup.- and R.sub.3 (R.sub.1 R.sub.2 P.sup.+ H).sub.n nX.sup.- ; and combining the phosphonium salt with a transition metal salt of the formula MY.sub.m wherein M is a transition metal, and Y is the anion of a weak acid thereby forming a cationic transition metal catalyst.
