摘要:
An ultraviolet-curable liquid developer contains a cationically polymerizable liquid monomer, a photoinitiator, and a toner particle insoluble in the cationically polymerizable liquid monomer. The cationically polymerizable liquid monomer is a vinyl ether compound, and the photoinitiator is a compound having a particular structure.
摘要:
Gegenstand der vorliegenden Erfindung ist ein neues Verfahren zur Herstellung von niederviskosen Copolymerisaten von Maleinsäuremonoalkylester und Vinylalkylethern, das dadurch gekennzeichnet ist, daß die Copolymerisation von Alkylvinylether mit einer Mischung, bestehend aus Maleinsäureanhydrid und Maleinsäuremonoalkylester durchgeführt wird. Die Steuerung der spezifischen Viskosität wird durch die Einstellung eines bestimmten Maleinsäureanhydrid/Maleinsäuremonoalkylester-Verhältnisses erreicht.
摘要:
A polar-group-containing olefin copolymer which comprises 99.999 to 80 mol% of structural units derived from at least one of ethylene and ±-olefin having 3 to 20 carbon atoms and 20 to 0.001 mol% of structural units derived from at least one polar-group-containing monomer which contains an epoxy group and is represented by the following structural formula (I) or following structural formula (II), the polar-group-containing olefin copolymer being a random copolymer obtained by copolymerization in the presence of a transition metal catalyst and having a linear molecular structure.

摘要:
A process is described for the production of copolymers derived predominantly from a monomer, e.g. tert-butylstyrene, having a very low solubility in water, by low temperature emulsion polymerisation in a medium consisting substantially of water alone, under specified reaction conditions; high levels of conversion of monomer are achieved. The copolymer products are useful as additives to liquid hydrocarbon fuels for the purpose of reducing the tendency of the fuels to disseminate into mists under conditions of shock.
