Effect of a Plasticizer on the Properties of Elastomers Based on Polyester with Urethane–Hydroxyl Hard Blocks

Urethane-containing elastomers based on polyesters with various urethane–hydroxyl hard blocks were studied. The strength and glass transition point of the elastomers with urethane–hydroxyl hard blocks can differ significantly depending on the extent of the phase segregation. Di(2-ethylhexyl) sebacat...

Summary:Urethane-containing elastomers based on polyesters with various urethane–hydroxyl hard blocks were studied. The strength and glass transition point of the elastomers with urethane–hydroxyl hard blocks can differ significantly depending on the extent of the phase segregation. Di(2-ethylhexyl) sebacate and tri- n- butyl phosphate efficiently decrease the glass transition point of the elastomers synthesized.
