MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202517022697 A) filed by Borealis Ag, Vienna, on March 13, for 'propylene/ethylene/1-butene terpolymer compositions with multimodal base polymer.'

Inventor(s) include Fawaz, Joel; Wang, Jingbo; Gahleitner, Markus; Bernreitner, Klaus; and Leskinen, Pauli.

The application for the patent was published on May 30, under issue no. 22/2025.

According to the abstract released by the Intellectual Property India: "A propylene/ethylene/1 -butene terpolymer composition, comprising a) a multimodal base polymer (TP) in an amount from 95 to 99.9 wt.-% relative to the total weight of the propylene/ethylene/1-butene terpolymer composition, with the following properties: i. a melt flow rate (MFR2) in the range from 3 to 12 g/10 min, as determined according to ISO 1133 at 230 C at a load of 2.16 kg; ii. a content of 2,1 -regiodefects in the range from 0.1 to 1.0 mol-%, as determined according to quantitative 13C-NMR spectroscopy analysis; iii. an ethylene content (C2) in the range from 1.0 to 4.0 mol-%, as determined according to 13C-NMR spectroscopy; and iv. a 1 -butene content (C4) in the range from 3.0 to 10.0 mol-%, as determined according to 13C-NMR spectroscopy; v. a xylene cold soluble content (XCS) in the range from 0 to 3.0 wt.-%, as determined according to ISO 16152; wherein the multimodal base polymer (TP) comprises: al) a first terpolymer fraction (TP 1), in an amount of from 50 wt.- % to 80 wt.-% relative to the total weight of the multimodal base polymer (TP), with a melt flow rate (MFR2) in the range from 1 to 10 g/10 min, as determined according to ISO 1133 at 230 C at a load of 2.16 kg; and a2) a second terpolymer fraction (TP2), in an amount of from 20 wt.-% to 50 wt.-% relative to the total weight of the multimodal base polymer (TP), with a melt flow rate (MFR2) in the range from 5 to 30 g/10 min, as determined according to ISO 1133 at 230 C at a load of 2.16 kg; b) additives in an amount of from 0.1 to 5 wt.-% relative to the total weight of the propylene/ethylene/1-butene terpolymer composition selected from the group consisting only of antioxidants, anti -blocking agents, UV-stabilizers, anti-scratch agents, mold release agents, lubricants, anti-static agents, pigments, and mixtures thereof; wherein the propylene/ethylene/1-butene terpolymer is essentially free of acid scavengers."

The patent application was internationally filed on Sept. 20, 2023, under International application No.PCT/EP2023/075918.
