Abstract
Official abstract text for this publication.
Provided are a plasticizer for a resin composition including any one or more selected from a polyvinyl chloride resin, a polyurethane resin, an epoxy resin, a polycarbonate resin or a biodegradable resin, which has excellent mechanical properties such as tensile strength, elongation and hardness, and shape processability, and particularly has excellent flexibility at low temperatures, does not cause bleeding because compatibility with the resins is good, and has excellent transparency, heat resistance, cold resistance and durability, and a resin composition including the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition comprising: a polyalkylene carbonate resin; and a plasticizer represented by the following Formula 4: wherein, R 8 is straight- or side-chained C1-C8 alkylene, C5-C10 cycloaliphatic alkylene or C6-C12 arylene, R 9 and R 10 are each independently a straight- or side-chained C1-C18 alkyl group, a C5-C10 cycloaliphatic alkyl group or a C6-C12 aryl group, and p is 1 to 40, and the resin composition has an elongation of 405% to 495%. 2. The resin composition of claim 1 , wherein R 8 is ethylene or propylene, R 9 and R 10 are each independently a methyl or acetyl, and p is 4 to 8. 3. The resin composition of claim 1 , wherein the resin composition includes 1 to 70 parts by weight of the plasticizer based on 100 parts by weight of the resin. 4. The resin composition of claim 1 , wherein the polyalkylene carbonate is polypropylene carbonate or polyethylene carbonate. 5. The resin composition of claim 1 , wherein the weight average molecular weight of polyalkylene carbonate resin is 2,000 to 3,000,000 g/mol. 6. The resin composition of claim 1 , wherein the specific gravity of the polyalkylene carbonate resin is 1.0 to 1.3.
