Preparation and Crosslinking of Acrylate Copolymer Latex Containing Carboxyls/Epoxy Resin——Composition Design and Preparation of Acrylate Copolymer Latex Containing Epoxy Resin
The coating made from AAFEE had excellent properties if n (epoxy group)∶ n (hydroxyl)∶ n (amber anhydride)=3∶7∶6,3∶7∶5. More than 60% of the carbon carbon double bonds in AAFEE was reacted under UV light for 15 s.
It has been proved by chemical analysis and IR that the synthesized compounds, if E/I > 1, contain OX rings and a few IS rings with epoxy as end groups.
A relatively higher relative molecular mass linear polymer is obtained with the mass ratio of AFEE/EDA=75/1(the mol ratio of epoxy group and amino group = 1.68∶1).
It was found that the glossiness of the polymer was reduced from 89 8% to 70 9%, Ca 2+ stability from 9 7 mL to 2 7 mL, pencil hardness from 2B to 3H and the water absorption from 24 9% to 0 2% with the increase of epoxy siloxane, respectively.
The copolymer structure containing epoxy groups was demonstrated from the 1H nuclear magnetic resonance (1H NMR) spectrum.

Two β-amylase formers, strains No.21 and No.90, were isolated from soil. Three pieces of enzyme secreted respectively from No.21, No.90, and ATCC 8523, the known β-amylase former, were purified by fractionation with(NH_4)_2SO_4, followed by affinity chromatography on Epoxy Activated Sep- hatose 4B coupled with α-cyclodextrin. The product(maltose)of these partially purified preparations had a β-configuration. thus these enzymes are specific β-amylase. The isoelectric ponts of No.21 and No.90 -amylases...
This paper reports the PTC synthetic method of Phthalic anhydride of bis(3-ch1oro-2-hydroxypropyl) ester Using the quarternary ammonium salt as a catalyst the product is directly synthesized form phthalic anhydrid, water and epoxy chloropropane, with an esterification yield more then 95%. The paper studies the effects on the yield of the various factors e. g. reaction temperature, time, catalyst rate, etc.
