Abstract: A liner for repairing damaged pipes, such as underground sewer or gas pipes is disclosed. The liner comprises a TPU coating on a fibrous mat of non-woven fabric. The TPU coating is a high heat resistance polyester TPU which allows an epoxy resin/amine to be saturated in the non-woven fabric and the cure initiated by the use of steam or hot water. The cured epoxy resin converts the liner from a flexible state to a rigid state as the liner is cured in place inside the pipe. The TPU containing liner may also be used with thermoset resins other than epoxy resins, such as polyester resins and vinyl ester resins.
Abstract: Disclosed are multi-purpose polymers that are the polymerization product of a monomer mixture comprising at least one amino-substituted vinyl monomer; at least one nonionic vinyl monomer; at least one associative vinyl monomer; at least one semihydrophobic vinyl surfactant monomer; and, optionally, comprising one or more hydroxy-substituted nonionic vinyl monomer, crosslinking monomer, chain transfer agent or polymeric stabilizer. These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial rheological properties in acidic aqueous compositions, and are compatible with cationic materials. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.

Abstract: Dithiocarbonate derivatives are disclosed, along with a process for preparing the same. The dithiocarbonate compounds can be utilized as initiators, chain transfer agents and/or terminators in controlled free radical polymerizations. The dithiocarbonates can be used to produce polymers having narrow molecular weight distribution. Advantageously, the compounds of the present invention can also introduce functional groups into the resulting polymers. The dithiocarbonate compounds have low odor and are substantially colorless.

Abstract: Disclosed are multi-purpose alkali-swellable and alkali soluble associative polymers, which are the polymerization product of a monomer mixture comprising: (a) at least one acidic vinyl monomer; (b) at least one nonionic vinyl monomer; (c) a first associative monomer having a first hydrophobic end group; (d) a monomer selected from the group consisting of a second associative monomer having a second hydrophobic end, a semihydrophobic monomer and a combination thereof; and, optionally, (e) one or more crosslinking monomers or chain transfer agents. When monomer (d) is an associative monomer, the first and second hydrophobic end groups of monomers (c) and (d) have significantly different hydrophobic and/or steric character from one another. The multi-purpose associative polymers surprisingly provide desirable rheological and aesthetic properties in aqueous media.
