A COLLEGE COURSE IN RUBBER TECHNOLOGY. 



REALIZING its advantages of location in ilic greatest rubber 

 manufacturing city of the world, the Municipal University 

 of Akron, Ohio, oiTers, in connection with its regular courses 

 in chemistry, a course in the chemistry of india rubber, which 

 is designed to prepare young men who have had a preliminary 

 training in chemistry to enter the rubber industry with a theo- 

 retical and practical knowledge of chemistry as applied to the 

 manufacture of rubber products. 



The course at Akron is an advanced one, the ininimuni pre- 

 requisite requirements being at least three years of college chem- 

 istry, including general chemistry, eight credit hours, and six 

 credit hours each of qualitative analysis, quantitative analysis, 

 and organic chemistry. It covers a period of two semesters, 

 starting in September of each year, and the curriculum consists 



Akrox Mt 



IP.\L I'xrvERSITV LaBc-iR.' 



of lectures, recitations, laboratory work, and visits to lactones, 

 of which .'\kron offers plenty, embracing virtually every im- 

 portant line of rubber manufacture. 



A general outline of the work follows : 



Crude Rubber. — Sources (including discussion of the latex 

 and coagulation), * washing and drying, * analysis, * chemical 

 properties, *physical properties, structure. 



Compounding Ingredients. — Sources and manufacture, 

 * analysis, * use. 



Vulcanized Rubber.—* Analysis, * physical testing, theory of 

 vulcanization. 



Rubber Compounding and Vulcanizing. — Calculating costs 

 and gravities of formulas, *compounding, *vulcanizing, 

 *physical testing. 



Rubber Reclaiming.—* Methods, * analysis and testing. 



Bal.ata .and Gutta Percha. — Properties and uses. 



Visits to Factories. — The topics are fully discussed in the 

 lectures, and those indicated by stars are further developed in 

 the laboratories, which are fully equipped to carry on the neces- 

 sary chemical work and provided with modern apparatus for 

 w^ashing, compounding, vulcanizing, reclaiming, and testing 

 rubber. The student thus acquires knowledge and actual ex- 

 perience in these processes, and in near-by factories becomes 

 familiar with the details of various manufacturing methods 

 impossible to conduct in the laboratory. With preparation in 

 the technology of rubber he is placed in a position to develop 

 into a valuable man in the laboratory, factory or sales force. 



The need for such a course is well indicated by the number 

 of situations open to skilled rubber men, while the success of the 

 course is shown by the fact that calls for graduates are received 

 from all parts of the United States, and that these students 

 have been uniformly successful in holding their positions.
