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.

Preformed multi-acid adducts useful for grafting polyolefin polymers

A process for the manufacture of a polyphenol compound such as bisphenol-A by introducing into a reaction zone a phenolic compound reactant, a carbonyl compound reactant, and a catalyst promoter comprising a dithioketal compound, and reacting the ingredients within the reaction zone in the presence of an acid catalyst.

Catalyst promotor for the manufacture of polyphenols

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.

Polyfunctional polyolefins

Biodegradable and/or compostable polymers are made from isoprene, 2,3-dimethyl-1,3-butadiene or like conjugated dienes and a crosslinking agent having a cleavable linking group such as ethylene glycol dimethacrylate. These polymers can be used to make absorbent foams that are useful in absorbent articles such as diapers, as well as other biodegradable articles such as films, and latexes useful as binders and adhesives.

Foam filter material and process to prepare foam filter material

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.

Preparation of transition metal catalysts from phosphonium salts

A polyketone is provided wherein the polyketone is water soluble and curable. A method to make a such a polymer is also disclosed, the method including the steps of: providing a polyketone, the polyketone comprising 1,4-diketone units; contacting the polyketone with a diamine wherein the diamine comprises one nitrogen which is more reactive than another of the nitrogens under conditions effective to incorporate the more reactive nitrogen in the polyketone; contacting the polyketone having the diamine incorporated into the polyketone with maleic anhydride under conditions effective to react the less reactive nitrogen with the maleic anhydride; contacting the polyketone having maleic anhydride incorporated thereto with a strong base; and recovering a functionalized polyketone wherein the functionalized polyketone is water soluble and curable.

Water soluble polyketones

Polymers are made from 1,3,7-octatriene or like conjugated polyenes and a crosslinking agent having at least 2 activated double bonds such as ethylene glycol dimethacrylate. These polymers can be used to make absorbent foams that are useful in absorbent articles such as diapers, as well as latexes that are useful as binders and adhesives.
