Curing reaction and product properties of polysulfones terminated with active functional groups
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
The curing processes of maleimide-terminated polyether sulfone oligomers ( M n from 1100 to 3000) and ethynyl-terminated polysulfone prepolymers ( M n from 2600 to 12000) were investigated by means of DSC. The ...
The effects of excise taxes and regulations on cigarette smoking
(Elsevier, 1991-05)
We estimate a generalized linear model to examine adult and teenage cigarette demand. Our analysis focuses on the extent to which exice taxes and regulations restricting smoking in public places affect cigarette consumption. ...
Preparation and characterization of maleimide-terminated poly(arylene ether sulfone) oligomers of various molecular weights
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
A new variation in the bismaleimide (BMI) resin family, maleimide-terminated poly(oxy-1,4-phenylene sulfonyl-1,4-phenylene) oligomers, has been synthesized. The preparation of oligomers ( n = 1–12) is described in this ...
A quantitative adhesion test for thin polymer films on silicon substrates
(Wiley Subscription Services, Inc., A Wiley Company, 1991-10-05)
The standard 90° peel test was modified in order to apply it to testing adhesion of thin polymer films to surfaces of silicon substrates, such as the silicon nitride passivation layer used in our solid-state chemical ...
