Abstract
A polymerization process and reactor utilizes a high power shock producing device for introducing high energy pulses shock waves to a body of constituent monomer molecules for breaking and making bonds. The high energy pulsed shock waves are generated and introduced into a body of the constituent monomerics to break the molecular bonds and create new bonding by a hollow piezoelectric shock tube mounted in an autoclave. A stirrer is operated simultaneously to stir away the new bonding sites and make them available for linkage to another monomer contained in the reactor vessel.

A polymerization method comprising placing polymerizable constituent monomer molecules in an autoclave having a heated reactor vessel for receiving said constituent monomer molecules, immersing the end of a high energy piezoelectric shock producing device in said constituent monomer molecules and then electrically charging said piezoelectric shock producing device to a high voltage (E) via a pair of electrodes on said piezoelectric shock producing device, operating an discharge switch means in shunt with said pair of electrodes for periodically discharging said piezoelectric shock producing device through said electrical switch and thereby producing high energy mechanical shock waves, the energy of which are proportional to the square of said high voltage (E.sup.2) and inversely proportional to the impedance (R) of said piezoelectric shock producing device, said high energy mechanical shock wave being capable of breaking some of the covalent and bivalent bonds of constituent monomer molecules in said reactor vessel.
A polymerization reactor comprising, an autoclave having a heated reactor vessel for receiving constituent monomer molecules, a high energy piezoelectric shock producing device mounted in said reactor vessel, said piezoelectric shock producing device having a pair of electrodes thereon and an impedance R, high voltage supply means connected to said pair of electrodes for electrically charging said piezoelectric shock producing device to a high voltage (E), a normally open electrical switch means connected in shunt with said pair of electrodes for periodically discharging said piezoelectric shock producing device, means for periodically operating said switch closed and thereby producing high energy non-ultrasonic mechanical shock waves in said constituent monomers only on closure of said switch and the discharge of said high voltage, said high energy mechanical shock wave being proportional to the square of said high voltage (E.sup.2) divided by said resistance (R) and being capable of breaking some of the covalent and bivalent bonds of constituent monomer molecules in said reactor vessel.
A high power polymerization reactor comprising a reactor vessel for receiving constituent monomers, a piezoelectric shock element in said vessel, a pair of electrodes on said piezoelectric shock element, a high voltage source, a resistor element coupling said high voltage source to said pair of electrodes for automatically charging said piezoelectric shock element to a high voltage (E), switch means connected in parallel with said pair of electrode for repeated discharge of the charged piezoelectric shock element to produce repeated non-ultrasonic mechanical shock waves, respectively, which, in turn, break some of the bonds and prepare new bonding sites in said constituent monomers.
A polymerization reactor comprising,
- an autoclave having a heated reactor vessel for receiving constituent monomer molecules,
- piezoelectric shock producing device having one end mounted on a wall of said reactor vessel and another end adapted to be immersed in said constituent monomers, said piezoelectric mechanical shock wave producing device having a pair of electrodes thereon,

- electrica switch means connected between said pair of electrodes,
- control means for periodically closing said switch to directly connect said electrodes together and periodically discharge said piezoelectric shock producing device and thereby produce high energy mechanical shock waves in said constituent monomers only when said electrical switch means is closed to directly connect said electrodes together and discharge said piezoelectric shock producing device, said high energy non-ultrasonic mechanical shock wave being capable of breaking some of the covalent and bivalent bonds of constituent monomer molecules in said reactor vessel.
