Claim\n\n   \n1)  A process for production of elastomers comprising  \npolycondensation of triazine ring-containing dicarboxylic acidor dicarboxylic acid diester shown by the following formula:  \n[where R is hydrogen or alky1 group;X is hydrogen,alky1,aryl,alkoxy,aryloxy,amino or imino group;Y is oxygen and(where R′is hydrogen or alkyl group)]with poly(alkyleneoxide)glycol.  \n# 3.  Detailed Description of Invention\n\n   \nThe present invention relates to a process for production ofnovel elastomers having great elasticity as well as excellenttensile strength,light resistance and heat resistance.  Moreparticularly,the present invention relates to a process forproduction of novel polymers having great elasticity useful forproduction of various products,e.g.,fibers,films and othermolded products which require elasticity as an importantcharacteristic.  \nIt is a well known fact from the theory of rubber elasticitythat elastomers are obtained by block copolymerization of  \nappropriate low melting point segment and high melting pointsegment.  Particularly,block copolymers wherein hydrazine isused as a high melting point segment and polyester or polyetheris used as a low melting point segment have already beendeveloped as urethane group elastomer fiber.  However,thiselastomer fiber has very poor physical properties in view ofheat discoloring property,light resistance,chemical resistanceand the like compared with conventionally known and widely usedsynthetic fibers.  \nIt is an object of the present invention to provide a processfor production of polyester ether group elastomers which,quitedifferent from the abcvementioned type of elastomer,can provideelastomer fiber forms and other molded products having greatelasticity and strength as well as excellent heat resistance(heat behavior),light resistance and the like.  \nIn accordance with the present invention,it is possible toproduce novel elastomers having various properties mentionedabove by polycondensation of triazine ring-containing  \ndicarboxylic acid or dicaroboxylic acid diester shown by thefollowing general formula:  \n{where R is hydrogen or alkyl group;X is hodrogen,alkyl,aryl,alkoxy,aryloxy,amino or imino group;Y is oxygen orR′is hydrogen or alky1 group)]with poly(alkylene oxi  \nNormally,triazine ring-containing dicarboxylic acid or diestershown by the abovementioned general formula is produced bymaking cyanuric acid chlordie or  \n2-substitute-4,6-dichlor-s-triazine-to react with amino  \ncarboxylic acid or ester thereof,oxycarboxylic acid or esterthereof,mercaptocarboxylic acid or ester thereof etc.by aconventionally known method.  \nConcrete examples of triazine ring-containing dicarboxylic acidor diester thereof used in the method of the present inventionare 2-amino-4,6-bis(p-carboxyanilino)-s-triazine,2-methylamino-4,6-bis(p-carboxyanilino)-s-triazine,2-dimethylamino-4,6-bis(p-carboxyanilino)-s-triazine,2-ethylamino-4,6-bis(p-carboxyanilino)-s-triazine,2-diethylamino-4,6-bis(p-car boxyanilino)-s-triazine,2-anilino-4,6-bis(p","cbCainXUkzxgw8JR","https://ap.wps.com/l/cbCainXUkzxgw8JR","pdf",767970,28,"English","# 1.
