摘要：
This paper explains a method for measuring shrinkage and spatial thermal expansion of unsaturated polyester resins. These can be used to determine the progress of curing during polymerization. The twin-capillary dilatometer used employs any suitable and convenient fluid medium, e. g. alcohols, oils etc. and is easy to operate.
