Definitions

• a non-urethane thickener is disclosed in U.S. patent 3,770,684 which teaches latex compositions containing from about 0.1% to about 3.0% of a compound of the general formula R-X- (water soluble polyether) -X-R' wherein R and R' are water insoluble hydrocarbon residues; X is a connecting linkage selected from the group consisting of an ether linkage, an ester linkage, an amide linkage, an imino linkage, a urethane linkage, an sulfide linkage, or a siloxane linkage.
• R-X- (water soluble polyether) -X-R' wherein R and R' are water insoluble hydrocarbon residues
• X is a connecting linkage selected from the group consisting of an ether linkage, an ester linkage, an amide linkage, an imino linkage, a urethane linkage, an sulfide linkage, or a siloxane linkage.
• patent 3,770,684 also teaches that the preferred water soluble polyether is a polyethylene oxide polymer having a molecular weight of from 3,000 to 35,000 or an ethylene oxide-propylene oxide copolymer having a molecular weight of from 3,000 to 35,000.
• Each of B 1 -B 8 is an ester, amide, amine, ether, sulfide, disulfide, thiocarbamate, urea, urethane. thiourea, sulfate, phosphate, carbonyl, methylene, thioamide, carbonate, or imide linkage as disclosed above for A 1 and A 2 . While only one of B 1 -B 8 can be a urethane linkage each one of B 1 -B 8 can be identical when one of B 1 -B 8 is not a urethane linkage. For example, each or all of B 1 -B 8 can be an ether linkage or an ester linkage. The values of A 1 and A 2 are limited by the value of B 1 -B 8 such that when one of B 1 -B 8 is urethane, only one of A 1 and A 2 is also urethane.
• the adduct can be made by reacting a compound of the formula R 1 -(B'Z) 1 _ 8 wherein R 1 is defined as above and each B'Z is a precursor of an ester, amide, amine, ether, sulfide, disulfide, thiocarbamate, urea, urethane, thiourea, sulfate, phosphate, carbonyl, methylene, thioamide, carbonate, or imide linkage which when reacted with a polyether or an alkylene oxide will result in the formation of the respective linkage with a polyether so that each terminal atom of the functional groups of R 1 -(B'Z) 1-8 is bonded to a terminal atom of a polyether chain.
• a 1 and R 2 are defined as above and Y is a functional group capable of reacting with the terminal OH group of the adduct R 1 -(B) 1-8 -(AO) c -OH to form an ester, amide, amine, ether, sulfide, disulfide, urethane, thiocarbamate, urea, thiourea, sulfate, phosphate, carbonyl, methylene, thioamide, carbonate, or imide linkage between R 2 and -(AO) ß -.
• the dimer can be alkoxylated with an alkylene oxide to yield an adduct which can then be used in one of the preferred processes as disclosed herein.
• An example of a compound wherein R 1 is an aliphatic radical having a valence of eight and which contains a hetero atom can be made starting with tripentaerythritol or pentaerythritol trimer.
• the trimer can be alkoxylated with an alkylene oxide to yield an adduct which can then be used in one of the preferred processes as disclosed herein.
• An example of a compound wherein R 1 is an aliphatic radical having a valence of four and which contains a hetero atom can be made starting with a dianhydride ketone as taught by U.S.
