摘要：
1. A PROCESS FOR DETERMINING THE PROPORTION OF MONOMERS IN A COPOLYMER, WHEREIN THE MONOMERS HAVE DIFFERENT DIELECTRIC CONSTANTS, SAID PROCESS COMPRISING CONTACTING A CAPACITIVE DETECTOR RESPONSIVE TO THE DIELECTRIC CONSTANT OF FLUIDS WITH A FLUID STREAM OF SAID COPOLYMER IN A ZONE OF RELATIVELY CONSTANT TEMPERATURE AND PRESSURE,
MEASURING THE CAPACITANCE OF THE CAPACITIVE DETECTOR WHILE IN CONTACT WITH THE FLUID STREAM AND COMPARING THE VALUE OF THE CAPACITANCE SO MEASURED WITH A PREDETERMINED REFERENCE VALUE.
