The present invention relates to a compound according to formula (1)

Phenalkamine curing agents and epoxy resin compositions containing the same

The present invention relates to polyglycidyl ether compounds containing at least three mono- or divalent radicals A of the general formula wherein R.sub.1 represents (i) a straight chain or branched alkyl groups of 1 to 16 carbon atoms, which may be substituted by one to four chlorine or bromine atoms, or (ii) a straight chain or branched alkenyl group of 2 to 6 carbon atoms, which may be substituted by one to four chlorine or bromine atoms, or (iii) a phenyl or naphthyl group, optionally substituted in the ring or rings by one or two chlorine or bromine atoms or by one or two alkyl groups, each of 1 to 10 carbon atoms, and having in all from 7 to 30 carbon atoms, or (iv) a phenylalkyl or naphthylalkyl group, optionally substituted in the ring or rings by one or two chlorine or bromine atoms or by one or two alkyl groups, each of 1 to 10 carbon atoms, said phenylalkyl or naphthylalkyl group having in all from 7 to 30 carbon atoms, or (v) a mononuclear cycloalkyl group of 3 to 6 carbon atoms, or (vi) a mononuclear cycloalkylalkyl group of from 4 to 10 carbon atoms and R.sub.2 represents hydrogen or a straight chain or branched alkyl groups of 1 to 9 carbon atoms. The invention further relates to processes for making and using the polyglycidyl ether compounds.

Polyglycidyl ethers of secondary alcohols, their preparation, and

The present invention relates to the preparation of di-secondary alcohols comprising the reaction of an alcohol and a diglycidyl ether of a dihydric phenol in the presence of a catalyst of the formula (IV):

Process for the preparation of addition products of epoxides and alcohols

The present invention relates to a process for the preparation of a glycidyl ether of a di-secondary alcohol with a monomer content of about 80% to about 90% of the formula (I) ##STR1## comprising the steps of: (a) reacting a di-secondary alcohol of the formula (II) ##STR2## with epichlorohydrin in the presence of an alkali and a phase transfer catalyst to produce a glycidyl ether with a monomer content of about 60% to about 75%; and

Process for the preparation of glycidyl ethers of di-secondary alcohols

Carboxyl-terminated and hydroxyl-terminated aliphatic polyester compositions derived from 1,4-cyclohexane-dicarboxylic acid, and a glycol component comprising primarily of cycloaliphatic diols and modifying aliphatic glycols, said polyesters being optionally stabilized by the presence of ultraviolet light absorbing compounds and/or hindered amine light stabilizers and being used in powder coating formulations to provide improved weatherability thereto.
