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.

A method of using compositions as foam regulators for water-based systems with a tendency to foam is provided. The method employs a block copolymer containing ester groups corresponding to general formula (I): A--(CH.sub.2 CH.sub.2 O).sub.n --B (I) in which n is an integer of 4 to 300, A is an optionally polymeric hydroxycarboxylic acid function and B is hydrogen, an alkyl or alkenyl radical containing 1 to 22 carbon atoms, a phenyl or benzyl radical or has the same meaning as A. Also provided is a granular free-flowing foam regulating formulation which contains 0.5% by weight to 30% by weight of the block copolymer containing ester groups adsorbed onto from 70% by weight to 99.5% by weight of a granular, substantially inorganic phosphate-free support material.

摘要:
In the process described, cyclic polyimino ethers with .DELTA..sup.2 -oxazoline or .DELTA..sup.2 -5,6-dihydro-4H-1,3-oxazine structure are applied, alone or together with cyclic monoimino ethers of the same type, or with lactones, plus cationic polymerization catalysts, to solid surfaces and polymerized by heating. The process gives smooth, glossy coatings with high adhesive strength, hardness, and elasticity.
