AI Technical Summary

Problems solved by technology

However, most metal salts are incompatible with medium to low polarity polymers such as polypropylene, polyester and polycarbonate
This incompatibility can lead to insufficient antistatic performance and / or an unacceptable reduction in physical properties or clarity of the finished polymer

[0102]

[0103] CH 2 =CHCO 2 (CH 2 ) 2 N + (CH 3 ) 3 - N(SO 2 CF 3 ) 2 (11 g, 0.025 mol), 1.44 g acrylic acid (0.02 mol), 0.256 g VAZO 67, and 19.2 g MEK were added to a 1-oz (30-mL) jar. The jar was purged with nitrogen for 1 min and then sealed. The bottle was heated at 60°C for 8 hours. A viscous solution (Solution A) was prepared.

[0104] For Example 1, 0.5 g of Solution A above was diluted with 0.5 g MEK, mixed with 0.11 g of CX-100, and coated onto PET film (23 microns nominal wet film thickness) using a No. 10 Meyer rod. The coating was baked at 120°C for 5 minutes.

[0105] For Example 2, 0.5 g of Solution A above was diluted with 0.5 g MEK and mixed with 0.22 g of EPOCROS WS500 and coated onto PET film using a No. 10 Meyer rod. The coating was baked at 120°C for 5 minutes.

[0106] For Example 3, 0.5 g of Solution A above was diluted with 0.5 g MEK and mixed with 0.11 g of EPON 824 Part A and coated onto PET film using a No. 10 Meyer rod. The hazy ...

Abstract

Antistatic polymers include divalent segments having the formulas (I) and (II) and wherein R1 represents an alkyl group having from 1 to 18 carbon atoms, R2 and R3 represent alkyl groups having from 1 to 4 carbon atoms, R4 represents an alkylene group having from 2 to 8 carbon atoms, and R5 independently represents H or methyl. Methods of making antistatic polymers are also disclosed.

Description

technical field [0001] The present disclosure relates broadly to antistatic polymers and methods for their preparation. Background technique [0002] Antistatics or antistatic agents are used to dissipate static electricity or static charge. The build-up of electrostatic charges can cause problems in the processing and use of many industrial products and materials. Carrying static electricity can cause materials to stick to each other or repel each other. Additionally, static charge buildup can cause objects to attract dirt and dust, which can cause manufacturing or contamination issues and can impair product performance. Sudden electrostatic discharges from insulating objects can also be a serious problem. Electrostatic discharges can act as a source of ignition when flammable materials are present, resulting in fire and / or explosion. [0003] Electrostatic charges are particularly problematic in the electronics industry because modern electronic devices are extremely s...
