标 题 :High yield synthesis of hydroxyl-containing cationic photoinitiators
发明人：CRIVELLO JAMES V
权利人:POLYSET CORP
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.

权利人:BASF AG
摘要:A process for purifying alkenyl compounds having a divalent or trivalent heteroatom in the alpha-position relative to the double bond by distillation comprises carrying out at least two distillations in which the purified alkenyl compounds are obtained from the gas phase by condensation, where the time between the first distillation after the synthesis of the alkenyl compounds and at least one further distillation is at least one day and the purified alkenyl compounds have an APHA color number of <30.

R 2 is H, or an alkyl group having 1-5 carbon atoms. R 3 is H or an alkyl group having 1-5 carbon atoms. R 4 is an alkyl group having 1-5 carbon atoms. R 5 is H or an alkyl group having 1-5 carbon atoms. R 6 is H or an alkyl group having 1-5 carbon atoms. R 7 is C(R 10 ) (R 11 ) wherein (R 10 ) is H, or an alkyl group having 1-5 carbon atoms, and (R 11 ) is H, or an alkyl group having 1-5 carbon atoms. The crosslinker is stable in a basic environment, but decomposable in an acidic environment.

摘要:Cross-linkable, olefinic polymers synthesized from mixtures of olefinic polymers and ethylenically unsaturated organosilane compounds, which can be grafted, by a 2-step method using thermally decomposing free radical-forming agents by heating the mixtures to a temperature of 30 DEG to 110 DEG C. below the softening temperature or the crystallite melting point of the olefinic polymers used and subsequently heating the mixtures to a reaction temperature of 10 DEG to 60 DEG C. below the softening temperature or the crystallite melting point of the olefinic polymers used. In the alternative, they can be grafted by a method involving the action of ionizing radiation with simultaneous absorption of organosilane compounds and the action of radiation. The method is suitable for producing films, sheets, fibers, panels, coatings, pipes, hollow objects, foamed materials and molded articles.
