标题:Initiator compositions and methods for their synthesis and use
发明人：CRIVELLO JAMES V
摘要:Cationic polymerization initiators of formula ##STR1## are disclosed. The acyl sulfonium salts of the present invention differ from known acyl sulfonium initiators in that the substituents R 2 and R 3 on the sulfur are larger and more complex than the lower alkyl and lower alkylene of known photoinitiators. Processes for the synthesis of the novel acyl sulfonium salts and prepolymer compositions containing them are also disclosed.

摘要:Synthesis use of a new class of diaryliodonium salt photo and thermal polymerization initiators in which the aryl groups are substituted with alkoxy group bearing hydroxy groups. Good to excellent yields are obtained of diaryliodonium salts in which the aryl groups are substituted with long chain alkoxy groups, which alkoxy groups also possess at least one hydroxyl moiety attached at the 2-position of an alkoxy group. The resultant salts have enhanced solubility when compared with their lower molecular weight counterparts. The hydroxyl groups serve as chain transfer agents; and, in cross linking UV-induced cationic polymerizations, the hydroxyl groups effect marked accelertion on polymerization rates. The salts also have excellent compatability with nonpolar monomers such as epoxidized oil and poly(1,2-butadience oxide) and provide further benefits when they are used along with copper cocatalysts in thermally curable polymer systems. In the latter form of cases, the secondary hydroxyl group serves as a reducing agent for the copper (II) complex.

摘要:The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkoxylating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea.

摘要:A crosslinkable thermoplastic resin composition may include a polymer formed from the reaction between a bis-benzoxazine monomer and a bifunctional comonomer having phenol, amine, and/or thiol functional groups, wherein the polymer contains at least one crosslinkable group. A method of forming a crosslinkable thermoplastic resin composition may include reacting a bis-benzoxazine monomer and a bifunctional comonomer to form a polymer containing at least one crosslinkable group. A method of forming a cured thermoplastic resin may include curing the crosslinkable thermoplastic resin composition by applying an external stimulus.
