摘要： Organophilic clays are useful as an agent for separating the organic phase from oil-in-water suspensions, particularly from aqueous suspensions of coatings or paints. Illustrative other suspensions include oil spin suspensions, suspensions resulting from machine cuttings, industrial wastes, and used lubricants and coolants.

摘要： A water dispersible, modified polyurethane which is the reaction product of polyisocyanate, polyether polyol, modifying agent containing at least one pendant hydrophobic group and at least two active hydrogen moieties and capping agent. The modified polyurethane may also include a second type of modifying agent which does not have a pendant hydrophobic group. The modified polyurethane can be prepared by reacting the polyisocyanate and the polyether polyol and then adding the capping agent and finally the modifying agent with or without the second modifying agent. The modified polyurethane resists microbial attack, exhibits superior efficiency in thickening aqueous compositions under high shear conditions and achieves acceptable sag and leveling.

摘要： A compressed powder formulation which consists essentially of an organophilic clay and at least one topical agent. The formulation maintains its physical integrity upon handling thereby permitting the preparation of the formulation in the form of self- supporting sticks and exhibits an acceptable level of payout. Additionally, the formulation retains an acceptable level of payout even when contacted with water. A process of making the formulation by compressing a powderous mixture is also setforth.

摘要： A water dispersible, modified polyurethane which resists microbial attack, exhibits superior efficiency in thickening aqueous compositions and imparts improved leveling, is the reaction product of:
a) a polyisocyanate;
b) from 0.10 to 10.00 moles per mole of polyisocyanate of a polyether polyol;
c) from 0.015 to 3.400 moles per mole of polyisocyanate, of a modifying agent having the formula
wherein R represents a group containing from 0 to 10 carbon atoms, X is a group containing at least one active hydrogen moiety selected from primary amino, secondary amino, carboxyl and mixturesthereof, Y is a group containing at least one active hydrogen moiety selected from primary amino, secondary amino, carboxyl, hydroxyl, mercapto and mixtures thereof, the sum of (x + y) is an integer greater than 1, and X is at least 1; and
d) capping agent which is reactive with the reaction product of (a) the polyisocyanate, (b) the polyether polyol and the (c) modifying agent, and which is present in an amount sufficient to cap the said reaction product.
