摘要:
Polybutene-1 in type II form can be accelerated in a phase transformation to the stable polybutene-1 type I form by applying a volatile solvent such as n-hexane and allowing the solvent to evaporate. The phase transformation can be accelerated by additional treatment with heat below the melt temperature of about 90°C and/or ultrasonic sound.

摘要:
This disclosure relates to a continuous solution polymerization process where ethylene interpolymer products having an improved color index; for example, products having higher whiteness (Whiteness Index (WI)) and lower yellowness (Yellowness Index (YI)). Product color was improved by adjusting selected solution polymerization reaction conditions. The disclosed ethylene interpolymer products have improved color relative to comparative polyethylene compositions.

摘要:
The present invention relates to a process for preparing a bonding sheet for composing circuit substrate, comprising pre-treating glass fabrics with a pre-treating varnish having a same or close dielectric constant (DK) to glass fabrics being used. The present invention further relates to bonding sheets prepared by the process, as well as circuit substrate. The process for preparing circuit substrate of the invention, which has a lower cost, does not need to upgrade or adjust the equipments. The circuit substrates prepared thereby have less warp-wise and weft-wise difference in dielectric constant, and thus can effectively solve the problem of signal time delay.
