Title of Invention\n\nA process for production of elastomers  \n# 2.  Claim\n\n1)  A process for production of elastomers comprisingpolycondensation of a diimidodicarboxylic acid ordiimidodicar boxylic acid diester shown by the following formula:  \n(where R is hydrogen or alkyl group;and R′is aliphatic groupor aromatic hydrocarbon group)with poly(alkylene oxide)g1ycol.  \n# 3.   Detailed Description of Invention\n\nThe present invention relates to a process for production ofnovel elastomers having high 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 for which elasticity is 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 imido ether group elastomers which,quite different from the abovementioned type of elastomer,canprovide elastomer fiber forms and other molded products havinggreat elasticity and strength as well as excellent heatresistance(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 diimidodicarboxylic acid or  \ndiimidodicaroboxylic acid diester shown by the following generalf ormula:  \n(where R is hydrogen or alkyl group;and R′is aliphatic oraromatic hydrocarbon radical)with poly(alkylene oxide)glycol.  \nThe diimidodicarboxylic acid shown by the abovementioned general  \nf ormula which is used in the present invention has a meltingpoint of more than 300c,preferably more than 350c.  Thediimidodicarboxylic acid diester has a melting point of morethan 150C,preferably 200-350C.  They are normallyproduced by the known organic synthetic chemical treatmentmethod.  \nThe abovementioned diamines used are,for example,aliphaticprimary diamines,i.e.,hydrazine,ethylene diamine,  \ntetramethylene diamine,pentamethylene diamine,hexamethylenediamine etc.,aromatic primary diamines,i.e.,p-phenylenediamine,m-phenylene diamine,benzidine,diaminodiphenylmethane,diaminodiphenyl ethane,diaminodiphenyl ketone,diaminodiphenyl sulfone,diaminodiphenyl sulfoxide,  \ndiaminodiphenyl ether,diaminodiphenyl thioether,p-xylenediamine,m-xylene diamine etc.,alicyclic primary diamines,  \ni.e.,4,4'-dic","cbCaifiLHQIi1XAl","https://ap.wps.com/l/cbCaifiLHQIi1XAl","pdf",713897,"English","# 1.
