Abstract: The present invention relates to a lactone-modified epoxy resin which is highly flexible and has improved heat resistance, water resistance, low- temperature properties and miscibility. The present invention also relates to a method of preparing such a lactone- modified epoxy resin and to compositions containing such a resin. The lactone-modified epoxy resin of the invention is obtained by reacting 97 to 5 parts by weight of a hydroxyl group-containing epoxy resin with 3 to 95 parts by weight of epsilon - caprolactone.

Abstract: A process for producing a lactone polymer comprises reacting an ester compound synthesized from an alcohol and an acid or acid anhydride with a lactone and a ring-opening polymerization initiator. When the ester compound is a polyester the thus produced lactone polymer is effective for preventing shrinkage of thermosetting resins, particularly unsaturated polyester resins.

Abstract: PURPOSE:To provide a thermosetting resin compsn. which has excellent storage stability, gives cured articles having excellent heat resistance, electrical characteristics, etc. and is suitable for use as an electrical material, by blending an org. Al compd. and an organosilicon compd. with an epoxy resin having a specified structure. CONSTITUTION:An org. Al compd. (e.g. trisacetylacetonatoaluminum) and an organosilicon compd. (e.g. a compd. of formula V) contg. a hydroxyl or hydrolyzable group directly attached to a silicon atom are blended with an epoxy resin of formula I (wherein R1 is a residue of an org. compd. contg. 1-100 active hydrogen atoms; n1, n2,... nl are each 0-100 and the sum thereof is 1-100; lis 1-100; A is a group of formula II: X is a group of formula III or IV,, etc.; R2 is H, alkyl, etc.; at least one group of formula III must exist in formula I).

Abstract: PURPOSE:A novel fiber-reinforced plastic, consisting of a novel epoxy resin containing cyclohexane skeleton, hardener and reinforcing fibers and having improved weather and heat resistance. CONSTITUTION:(A) An epoxy resin, expressed by formula I [R1 is organic compound residue containing l active hydrogen atoms; n1-nl are integers 1-100 in which the sum is 1-100; l is an integer 1-100; A is substituted group- containing oxycyclohexane skeleton expressed by formula II [X is expressed by formula III, CH=CH2, etc., provided that at least one or more of X are expressed by formula III], (B) a hardener, e.g. diethylenetriamine, and (C) rein forcing fibers are used by the well-known method to give the aimed product. The component (A) is obtained by for example, ring-opening polymerizing 4- vinylcyclohexene-1-oxide in the presence of an active hydrogen-containing com pound initiator and epoxidizing the resultant polyether resin with an oxidizing agent, e.g. a peracid, etc.
