Polymer composition

Abstract

The present disclosure relates to a polymer composition, and belongs to the technical field of PVB plasticizers. The polymer composition includes PVB and plasticizer, wherein the plasticizer has a structure as shown in a formula 1a or 1b; 1a R1-(C6H4)—(—OCH2CH2—)n—OH; 1b R2-(-OCH2CH2—)n—OH; wherein, n is an integer ranging from 2 to 30; R1 is C6-C16 aliphatic hydrocarbyl; and R2 is saturated or aliphatic hydrocarbyl having 12 to 20 carbon atoms in a linear carbon chain form. An elongation at break is a sign of softness, and it has been discovered through experimental study in the present disclosure that a substance with the structure as shown in the formula 1a or 1d has significant advantages relative to 3G8 when used as a PVB plasticizer, which is mainly reflected in the significant increase in the elongation at break.
