摘要:
A photocurable ethylenically unsaturated liquid coating composition consisting essentially of: 1- polyethylenically unsaturated material in which the ethylenically unsaturated groups are polymerizable groups which are not (meth)acrylate groups; 2- a polyamine resin; and 3- an hydroxyalkyl phenone photoinitiator to speed the cure. The photocure rate is also speeded by combining a tertiary amine-functional acrylic copolymer, an allyl-functional resin, and a maleate-functional resin in a weight ratio of about 15-65/5-45/30-70. In preferred practice both expedients are used to maximize the cure speed.

Gegenstand der Erfindung sind neue hydrophobe und/oder abhäsive Massen, reaktive Verdünner, Weichmacher mit einem Gehalt an einer monomeren, oligomeren und/oder polymeren methylgruppenreichen Kohlenwasserstoffverbindung und/oder deren Derivate mit der allgemeinen Formel worin bedeuten:
R 1 , R 2 , R 3 und R 4 = H, -CH 3 und/oder -CH 2 -CH 3 A und B = H, -CH 3 , -CH 2 -CH 3 und/oder ein Rest der vorstehenden allgemeinen Formel 2, und n = eine ganze Zahl zwischen 0 und 20.000.000, vorzugsweise 50 bis 1.000.000, insbesondere 50 bis 500.000, enthält und der Methylgruppengehalt mindestens 2,0, vorzugsweise 3.0 bis 4,0 Mol pro Monomer bzw. Monomereinheit beträgt. Mit diesen neuen methylgruppenreichen Verbindungen lassen sich auf wirtschaftliche Weise viele anorganische, metallorganische und/oder organische Stoffe hydrophob und/oder abhäsiv ausrüsten oder damit Filme oder Folien mit hydrophoben und/oder abhäsiven Eigenschaften herstellen.
Die flüssigen Verbindungen können auch als reaktive Verdünner und/oder Weichmacher eingesetzt werden.
摘要:
The invention relates to a resin composition based on a polymer and an ester of an unsaturated fatty acid and an alcohol containing a terminal unsaturation. The resin composition contains as ester a compound with the formula: R¹ - - O - R² where: R¹ is an alkyl radical with 10-24 carbon atoms and at least one non-terminal ethylenically unsaturated bond and R² is an organic group comprising one or more terminal allylether groups. The resin composition is substantially 100%-solid.
