Abstract: The present invention provides an amino resin composition for cleaning molds, that said composition is made of a thermosetting resin to which is a semi-cured amino resin composition or a semi-cured mixture thereof is added. The amino resin composition has decreased viscosity and increased tablet ability. When used to remove the soil on the surface of molds, the amino resin composition possesses good forming ability and good mold-cleaning effect so that the time needed for mold cleaning is efficiently decreased and the problem of a powder composition that can not be easily tabletted is overcome due to its excellent tablet ability.

Abstract: This invention discloses a flame retarding thermoplastic resin composition, which is comprised of (i) a thermoplastic resin and (ii) a phenolic resin compound as a flame retardant, wherein the phenolic resin compound contains a nitrogen-containing heterocycle and phosphorus. Since the flame retarding thermoplastic resin composition of this invention does not contain halogen, and has excellent flame retardant properties and high heat resistance, it is useful in producing parts and products in the fields of electronics, electricity and automobile.

Abstract: The present invention relates to a phosphorus-containing epoxy resin, which is an epoxy resin modified with a side chain having a reactive phosphorus-containing compound.

Abstract: This invention relates to an epoxy resin composition which comprises polyalkyl phenol resins or polyalkyl phenol epoxy resins or both, wherein the polyalkyl phenol resins are represented by formula (I): ##STR1## wherein Ra, Rb and Rc may be the same or different from each other and stand for C.sub.1-5 alkyl styryl or halogen respectively;n is an integer of 0 to 4;k is an integer of 0 to 3;l is an integer of 0 to 4; andm is an integer of 1 to 10;and the polyalkyl phenol epoxy resins, which are obtained by reacting polyalkyl phenol resins of formula (I) with epihalohydrins, are represented by formula (II): ##STR2## wherein G stands for ##STR3## while the other symbols are the same as those defined above. The epoxy resin composition of this invention is able to provide a reactivity at lower temperatures and provide lower viscosity when used as hardener resins, as compared with traditional phenolic novolacs.

Abstract: This invention relates to a process for preparing a high purity epoxy resin comprising reacting an aromatic compound containing hyroxyl or amino group with an excess amount of an epihalohydrin in the presence of hydroxides of alkali metal or alkali earth metal in one or more low-boiling aprotic cosolvents under normal or reduced pressure with dewatering to obtain a high purity epoxy resin with low level of hydrolyzable halides.

Abstract: A process for preparing carbonate compounds having the following formula: ##STR1## wherein R and R' are, the same or different, C.sub.1 -C.sub.6 alkyl group, a C.sub.3 -C.sub.6 cycloalkyl group, an optionally substituted C.sub.6 -C.sub.14 aryl group, an alkylaryl group, or an arylalkyl group is proposed; the process comprises reacting urea or derivatives thereof with appropriate alcohols or phenols and preparing the carbonate compounds via a multiple-step synthesis process.
