摘要:
A composition of matter comprising a resin obtained by a process comprising reacting at an elevated temperature an epoxidized ester of an unsaturated fatty acid with an aliphatic alcohol with a resin acid is provided. The equivalent ratio of epoxy groups of said epoxidized ester to carboxyl groups of said resin acid is in the range from 1.5:1 to 0.01:1. The resin is useful as a tackifier for adhesives and has a reduced tendency to crystallize.
摘要:
A process for modifying polymers containing carboxyl, hydroxyl and/or phenolic hydroxyl groups. In the process, the polymers are reacted with a delta.sup.2 mono- or bis-oxazoline, each substituted in the 2-position by an optionally substituted alkyl or alkenyl group containing from 7 to 23 carbon atoms. The modified polymers show reduced melt viscosities, lower adhesion and better slip characteristics than unmodified polymers.
