A study has been made of diisocyanates available for use in a polyurethane binder. Model polymers have been prepared using toluene diisocyanate TDI, diphenylmethane diisocyanate MDI, and dimeryl diisocyanate DDI. MDI and TDI both gave satisfactory properties. Although the properties of the DDI polymer were less desirable but adequate, no attempt was made to optimize the curing conditions, which should lead to better properties. Thus useful polymers can be obtained with any of these three diisocyanates. Factors such as cost, availability, and ease of handling appear more important in selecting which diisocyanates to use in a binder.
