(Hydroxyalkyl)aminophenol polymers and methods of use
Disclosed herein are polymers formed by the condensation of bis(hydroxycarbyl)-aminophenolic compounds with aldehydes. The condensation polymers include one or more repeat units having bis(hydroxycarbyl)amino functionality. The polymers are useful as antifoulants, antipolymerants, rheology modifiers, dehazers, polymerization retardants, surfactants, or a combination of these in one or more industrial process streams.
IN-SITU ALKYLPHENOL-ALDEHYDE RESINS
The invention relates to an in-situ process for preparing an alkylphenol-aldehyde resin. The process comprises the step of providing a raw alkylphenol composition. The raw alkylphenol composition comprises one or more alkylphenol compounds and at least about 1 wt % phenol. Each alkylphenol compound has one or more alkyl substituents. The raw alkylphenol composition is reacted directly, without pre-purification, with one or more aldehydes to form an in-situ alkylphenol-aldehyde resin. The invention also relates to an in-situ alkylphenol-aldehyde resin formed from the in-situ process, and its use in a tackifier composition and rubber composition. The tackifier composition and rubber composition containing the in-situ alkylphenol-aldehyde resin show, inter alia, improved tack performance.

ALKOXYLATED (HYDROXYALKYL)AMINOPHENOL POLYMERS AND METHODS OF USE
Disclosed herein are polymers formed by the condensation of bis(hydroxycarbyl)-aminophenolic compounds with aldehydes. The condensation polymers include one or more repeat units having bis(hydroxycarbyl)amino functionality. The hydroxyl groups of the bis(hydroxycarbyl)amino functionalities are available for further condensation with an epoxide, such as ethylene oxide, to yield a polyalkoxylated polymer. The polymers are useful as antipolymerants, polymerization retardants, surfactants, or a combination of these in one or more industrial systems.
Wafer laminate and making method
A wafer laminate has an adhesive layer (2) sandwiched between a support (1) and a wafer (3), with a circuit-forming surface of the wafer facing the adhesive layer. The adhesive layer (2) includes a light-shielding resin layer (2a), an epoxy-containing siloxane skeleton resin layer (2b), and a non-silicone thermoplastic resin layer (2c).

Method for solid freeform fabrication
The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. The deposited powder bed is heated to about 50 C. to about 170 C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.
