标 题 :Sugar backbone polymer and synthesis method
发明人：CHEN GUOSONG; Xue Cece; RAO ZIKUN
权利人:UNIV FUDAN
摘要:A polymer material, specifically a sugar backbone polymer and a synthesis method. A new type of sugar backbone polymer is prepared using a condensation and polymerization method. An addition reaction of alcohol-olefin is introduced into the synthesis of the sugar backbone polymer, to form a new functional primary sugar chain alternating polymer having alternating sugar and aliphatic units. It overcomes shortcomings of existing artificial chemical synthesis methods such as difficulty in controlling the stereoselectivity of the product, low molecular weight, cumbersome monomer preparation and few types. The molecular weight of the prepared polymer can reach 71,067 g/mol, and monomer preparation is simple.

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.

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.
