UN PROCEDIMIENTO PARA PRODUCIR UNA RESINA HIDROCARBONADA HIDROGENADA

摘要

Hydrogenated hydrocarbon resins from cyclopentadiene and/or substituted cyclopentadiene of softening point below 90 DEG C. and having a (Tg) as from 35 to 70 lower than the softening point with less than 12 wt. % of the resin having a molecular weight above 1000 are particularly useful as tackifiers in pressure sensitive adhesives especially in hydrogenated styrene/butadiene/styrene block copolymer adhesive formulations where their use can obviate the need for plasticizing oil.
