| abstract | PURPOSE:To improve dimensional stability by adjusting the coefft. of expansion with temp. and humidity of a biaxially oriented film consisting of poly-p-phenylene sulfide in a specific range. CONSTITUTION:A biaxially oriented film of which >=90mol% consists of poly-p- phenylene sulfide is used as a base in this invention. This film is provided with the expansion characteristics in which the max. coeffts. of expansion with the temp. and humidity at the longitudinal and transverse planes are respectively 9- 35X10<-6> deg.C<-1> and 0-5.0X10<-6>%RH<-1> and the difference between the max. value and min. value of the coefft. of expansion with temp. and humidity are respectively 0-8.0X10<-6> deg.C<-1> and 0-2.0X10<-6>%RH<-1>. The coeffts. of expansion are obtd. by setting adequately film forming conditions. The essential requirement for this film is that >=90mol% thereof consists of the constituting unit of the formula I . Para-halobenzene and alkali sulfide are brought into reaction in a polar solvent as a general method for polymerizing such poly-p-phenylene sulfide. |
