  • Patent number: 5137987
    Abstract: Thermosettable polyol resins for coating compositions are prepared by reacting a polyglycidyl ester of an aliphatic polycarboxylic acid and a di- to hexa-hydric aliphatic alcohol with an adduct of a di- to hexa-hydric aliphatic alcohol and a glycidyl ester of a branched aliphatic monocarboxylic acid with 5 to 15 C-atoms, said adduct having an epoxy group content of less than 0.2 meq/g.
    Type: Grant
    Filed: March 13, 1991
    Date of Patent: August 11, 1992
    Assignee: Shell Oil Company
    Inventors: Olivier L. P. Andre, Carien H. P. Gerets, Henricus P. H. Scholten
  • Patent number: 5098966
    Abstract: An aromatic polyglycidyl polyether resin having an average of 1.5 to 4.5 epoxy groups and 0.1 to 18 primary or secondary --OR groups per molecule, wherein from 5 to 95% of the --OR groups have the general formula --O--CH.sub.2 --CHOH--CH.sub.2 --O--C(O)--R', in which R' is a branched C.sub.4-17 alkyl group, the remainder of the --OR groups being hydroxyl groups, and a process for preparing the same wherein an epoxy compound (A) is reacted with one or more hydroxyl groups contained in a polyglycidyl polyether (B) of a polyhydric aromatic compound in the presence of an etherification catalyst (C), in which (A) is a glycidylester of a C.sub.5-18 branched aliphatic monocarboxylic acid, (B) is a polyglycidyl polyether having on average of from 1.5 to 4.5 epoxy groups and of form 0.1 to 18 primary or secondary hydroxyl groups per molecule, and (C) is a tin, zinc or iron compound.

  • Patent number: 5066763
    Abstract: An adduct of:a) one or more polyhydric alcohols of formula R(OH).sub.n in which R is an aliphatic or heterocyclic moiety of from 2 to 18 carbon atoms, the hydroxyl groups are attached to a primary carbon atom, or a secondary carbon atom in which the second hydroxyl group is attached to a carbon atom no more than 4 carbon atoms away from said secondary carbon atom, and n is an integer of from 2 to 6, andb) an at least equimolar amount of one or more monoepoxides of formula ##STR1## in which R' is an optionally substituted aromatic moiety of up to 14 carbon atoms,said adduct having a molecular weight distribution Mz/Mw of from 1 to 1.1, and a process for preparing the same.

  • Patent number: 5051492
    Abstract: A process for the preparation of a polyether resin having an epoxy group content of less than 0.2 meq/g and containing or average n/3-0.5 to n/3+2.5 primary hydroxyl groups, the process comprising reacting a glycidyl ester of a C.sub.9-11 branched aliphatic acid with an aliphatic primary polyhydric alcohol having n primary hydroxyl groups and 5 to 16 carbon atoms, n having a value of 3 to 6, in the presence of an etherification catalyst selected from a tin, zinc or iron compound.
