Monomers for Synthetic Rubber Production, in the production of synthetic rubbers. Some indication of the properties of these monomers will also be given. These processes have been gathered together in one chapter for convenience in order to avoid unnecessary subsequent repetition or cross-referencing, and also to avoid interruption of the

Outline of Polymerisation Methods, repeated many times over, and that the chemical reaction by which these molecules are produced from the corresponding monomers is known as polymerisation. Polymerisation reactions are classified into two broad groups:

Rubbers Obtained from Butadiene Derivatives,are of commercial importance at the present time. These are the rubbers which are obtained by the polymerisation of isoprene and of chloroprene respectively. These two types of rubber are rather disparate as regards nature, technology, and areas of application. Isoprene rubber is a general-purpose h

Rubbers Derived from Olefins and from Olefin Oxides,olefin rubber which has been produced commercially, namely, that which is obtained by copolymerising isobutene with minor amounts of a diolefin. It is convenient to note here also the existence of certain other similar olefin rubbers of very minor importance, and also to deal at the same time with t

Plasticised Polyvinyl Chloride (PVC),oride. The principal repeat unit present in polyvinyl chloride is shown at (LXXXIV). Polyvinyl chloride can be obtained in several forms, depending upon the method by which it is prepared. The common form is produced by . the free-radical polymerisation of vinyl chloride, and in the unplasticised st

Other Types of Synthetic Rubber,ical modifications of other synthetic rubbers. In this group, known collectively as the ., the main chain of the rubber molecule has been modified in such a way that it carries a minor number of pendant carboxylic-acid groups. There are several types of synthetic rubber which lend themselves to modi

Although, in the event, it has not proved possible to publish the full book in the form originally planned, it was apparent that, with some restructur

Novel Developments in the Technology of Synthetic Rubbers,r which is capable of being processed in a particular way. But these chemical variations are largely secondary to the processing technology by which the rubber is intended to be fabricated into the final product. Indeed, it has often been the case that the chemical variations have been dictated by the processing requirements.
