Abstract: Disclosed is a polyalkylene terephthalate type flame retardant resin composition comprising:(A) 100 parts by weight of a polyalkylene terephthalate resin,(B) 30 to 250 parts by weight of a filler,(C) 5 to 50 parts by weight of an organic halogen compound having a glycidyl group, and(D) 5 to 50 parts by weight of sodium antimonate,wherein heat resistance is improved and change in molding stability is small even when it is exposed to high temperatures during molding.

Abstract: A process for producing a novolak-type epoxy resin, which comprises reacting a halohydrin ether of a phenol compound with an aldehyde compound in the presence of an acid catalyst, and thereafter treating the product with a cyclizing agent to form an epoxy ring.

Abstract: A novel resin composition which is composed of molecules having an epi-bis type main skeleton of the formula ##STR1## X.sub.1 -X.sub.4 : H, Cl or Br R: H, or CH.sub.3and has a Gardner-Holdt viscosity of C to Z.sub.8 determined at 25.degree. C. for a solution in butyl carbitol in a concentration of 40% by weight.At least 40% of the entire terminal groups of the molecules of the novel composition consists of .alpha.-glycol groups of the formula ##STR2## wherein R represents hydrogen or methyl. The composition is more rapidly curable at lower temperatures than known epoxy resins having an epi-bis type main chain skeleton, and is useful as a paint or adhesive and also as an adhesion improver for other resins.
