FIELD: quality inspection of polymer materials. SUBSTANCE: inspection of polymerization degree of transparent article is conducted by loading sample twice, by exposing it to polarized light, by measurement of optical double-reflection and by determination of coefficient of optical sensitivity. In this case loading and measurement are performed at room temperature immediately after short-time heating to temperature of hardening of article. If coefficient of optical sensitivity has grown then degree of polymerization is inadequate but if it has not changed then degree of polymerization is adequate. EFFECT: improved authenticity of quality inspection. 1 dwg
