The method specified in claim 1 wherein the acidiccatalyst is an organic acid or its salt.  \n# Detailed explanation of the invention\n\nThe present invention concerns a method for manufacturinga novel phenolic resin.  More specifically,the present inventionconcerns a method for manufacturing a novel phenolic resinwherein a polyacetal resin is employed as a formaldehyde source.  \nPhenolic resins are representative thermocurable resins.Since they are inexpensive and have high dimensional stability,high strength,and durability,they are used extensively invarious fields as electrical insulators,molding materials,metal surface finishing agents,adhesives,etc.  \nThese phenolic resins are normally produced by reactingphenol and formaldehyde in the presence of an acidic or basiccatalyst.  As formaldehyde sources,the aqueous solution(i.e.,formalin)and the trimer(i.e.,paraformaldehyde)offormaldehyde have conventionally been used.  \nOn the other hand,polyacetal resins are thermocurable  \nresins which have high electrical insulation,mechanical strength,and stability,and they have been used as electrical insulatorsand various molding materials.  Defective products produced inthe production process and used waste products cannot be reusedand therefore are disposed of(e.g.,incineration,etc.).  \nThe present invention compiled exhaustive research on amethod for utilizing polyacetal resins,which have traditionallybeen discarded indiscriminately.  As a result,the present  \ninvention was completed after the following had been discovered:based upon the facts that polyacetal resins are corroded in asystem which contains both water and an acidic substance andthat stress cracks are produced,if this phenomenon is purposelyaccelerated for the purpose of eliciting a decomposition,it canbe used as a formaldehyde production source,and said decomposi-tion is significantly accelerated by the existence of a phenolicresin.  \nPut succintly,the objective of the present invention isto provide a method for manu facturing a phenolic resin whereina phenolic compound and a polyacetal compound are heated in thepresence of water and an acidic catalyst.  \nAs phenolic compounds employed in the method of the presentinvention,not only phenol but also alkylated phenols(e.g.,cresol,xylenol,etc.)may be effectively employed.  \nExamples of polyacetal resins include not only homopolymersbut also copolymers between formaldehyde and cyclic ethers(e.g.,ethylene oxide,etc.)and polyoxymethylene derivat","cbCaikwf4WOZ9Vv0","https://ap.wps.com/l/cbCaikwf4WOZ9Vv0","pdf",1181099,28,"English","# Claims\n## Detailed explanation of the invention","[{\"question\":\"What are the essential components of the phenolic resin manufacturing method?\",\"answer\":\"A phenolic compound and a polyacetal resin are heated in the presence of water and an acidic catalyst.\"},{\"question\":\"How does the method use polyacetal resin in the process?\",\"answer\":\"Polyacetal resin is employed as a formaldehyde source; decomposition is accelerated by the presence of a phenolic resin under acidic and aqueous conditions.\"},{\"question\":\"What catalyst types are covered by the claims?\",\"answer\":\"The claims include embodiments where the acidic catalyst is either an inorganic acid (or its salt) or an organic acid (or its salt).\"}]","METHOD FOR MANUFACTURING A PHENOLIC RESIN - read online free | PDF",1789969282,71]
