SSRN-W. R. Grace & Co. and the Neemix Patent (B) by Patricia Werhane, Kristi Severance. Mar 25,  · U.S. patent application Ser. No. ,, filed May 3, , and now abandoned (Wood et al, inventors) which is assigned to W. R. Grace & Co. teaches, in Example 21, a foamed polyurethane comprising an immobilized enzyme (urease), a method for preparing such immobilized enzyme, and a method for using it. The single most important factor in a company's success is the team that's leading the company. Industry, sector and description for W.R. Grace & Co.. The Company is engaged in specialty chemicals.

The process of claim 8 wherein the chemical free radical generating agent is selected from the group consisting of molecular oxygen; organic hydroperoxides and peroxides; blends of organic hydroperoxides and peroxides with tertiary amines; blends of organic hydroperoxies and peroxides with transition metal salts and blends of organic hydroperoxides and peroxides with tertiary amines and transition metal salts.

The process according to claim 6 wherein the composition includes 0. The process according to claim 10 wherein the free radical generating agent is U. The process according to claim 6 wherein the polyene is a member of the group consisting of methylene bisacrylamide 1,3 butylene glycol diacrylate, 1,4 butylene glycol diacrylate, diethylene glycol diacrylate, diethylene glycol dimethacrylate, 1,6-hexane diol diacrylate pentaerythritol tetraacrylate, bisphenol A dimethacrylate, N,N'-di hydroxyethyl dimethylhydantoin diacrylate, polyethylene glycol diacrylate, triethylene glycol diacrylate, trimethylolpropane triacrylate, bisphenol A diacrylate, 1,3 butylene glycol dimethacrylate, ethylene glycol dimethacrylate, polyethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate, triethylene glycol dimethacrylate, and trimethylol propane trimethacrylate, trimethylolpropane tricrotonate, and diethylene glycol dicinnamate.

The solid polythioether product prepared by the process of claim 6. A sealant consisting essentially of the composition of claim 1. An adhesive consisting essentially of the composition of claim 1. The composition of claim 1 where X is acryloxy or methacryloxy.

The composition of claim 16 wherein X is acryloxy. A composition capable of being crosslinked solely by radiation to form thioether groups between the carbon-to-carbon unsaturation of I and the thiol groups of II comprising: A process of forming a solid cured polythioether which consists essentially of 1.

This invention relates to a new curable composition which includes a liquid unsaturated component having at least two vinyl addition polymerizable groupings per average molecule and a polythiol component having a multiplicity of --SH functional groups per average molecule.

A photocuring rate accelerator is added to the composition when the curing is carried out using actinic radiation, e. It is well known in the art that addition polymerizable vinyl monomers may be polymerized by various means.Sep 15,  · So when Dr. Pal heard that W. R. Grace & Company had an American patent granted in for a pesticide based on neem, and that the patent was being challenged by an international coalition that.

The second patent is for a method of producing stable insecticide formulations containing high concentrations of azadirachtin. The US TNC, W.R.

W r grace co and the neemix patent

Grace has patents for neem-based biopesticides, including Neemix for use on food crops. Neemix suppresses insect feeding behaviour and growth in more than species of insects. W. R. Grace patented neemix, derived from seeds of neem tree, which grows naturally in India.

Patent was challenged on two general grounds: Neem seeds are natural and belong to everyone. Neem extracts and their effects are traditional knowledge in Indian culture.
