Aliphatic polyester compounds having highly branched structure as a plasticizer of polyvinyl chloride and flexible polyvinyl chloride blend containing the same |
摘要 |
<p>The present invention discloses aliphatic polyester compound having highly branched structure for polyvinylchloride plasticizer and polyvinylchloride blend containing the same. Aliphatic polyester compound having highly branched structure for polyvinylchloride plasticizer according to the present invention is formed by self-condensation polymerization of monomer having one carboxy functional group and two hydroxy functional groups. Since such aliphatic polyester having highly branched structure has superior compatibility with polyvinylchloride and never flows out contrary to the conventional liquid plasticizer having low molecular weight of phthalate, etc., the problems such as the disturbance of endocrine system of human body and the destruction of ecosystem due to the efflux of plasticizer is not caused and since the same has superior efficiency of plasticization, it is possible to give polyvinylchloride sufficient flexibility.</p> |
