Title: Maarten Antoon Jan Campman: Innovator in Polymer Production

Introduction

Maarten Antoon Jan Campman is a notable inventor based in Churra-Murcia, Spain. He has made significant contributions to the field of polymer production, holding a total of 7 patents. His work focuses on methods for producing high molecular weight polymers, particularly polycarbonates.

Latest Patents

One of his latest patents is a method of producing high molecular weight polymer. This invention provides methods for forming polycarbonate by combining a diaryl carbonate, a transesterification catalyst, an aliphatic dihydroxy compound, and a diacid compound in a reactor system. The temperature and pressure of the reactor system are adjusted to specific setpoints, and the reaction mixture is monitored to detect the initiation of the exothermic oligomerization reaction. After detection, the reactor setpoints are adjusted to allow the reaction mixture to form an oligomer mixture, which is then introduced to a polymerization reactor system. This process results in polycarbonate with a molecular weight of at least 9,000 g/mol.

Another significant patent involves the use of specific reaction conditions to produce polycarbonates with a molecular weight of greater than or equal to 25,000 g/mol. This method includes melt reacting an ester-substituted diaryl carbonate and a multifunctional compound in the presence of a catalyst. The resulting polycarbonates can include homopolycarbonates and aliphatic copolycarbonates, as well as thermoplastic compositions.
