A process for solvent welding pure polybutene-1, or blends or copolymer of polytbutene-1 to polybutene-1 where the polybutene-1 items are contacted with a solvent such as methylene chloride, tetrahydrofuran or cyclohexane and then contacted together within a variable period of time after ...
The average relative deviation and the average absolute deviation of the proposed model are 7.8% and 22.6 K, respectively. It is concluded that the proposal is useful for the prediction of the melting points for a wide range of ILs. This is a preview of subscription content, log in via an...
the consumption of benzophenone in cosmetics has been increasing. Recent studies believe that fluorescence is also a harmful ultraviolet light source, so the application range of benzophenone in the field of cosmetics has been expanding to hair conditioners, lotions and lipstick. In addition, it is...
The purpose of this paper is, (1) to con- firm that EVA systems really form the thermally reversible gels, and (2) to show that the theoretically derived eq 1 is also applicable for this copolymer gel. EXPERIMENTAL Materials acetate copolymers (EVA), which range in mole fraction of ...
A method for granulating a flexible polyolefin resin including: melting a flexible polyolefin resin by volatilization after polymerization; cooling the resin to a temperature in a range of the melting point of the resin (Tm-D) ±50° C.; and granulating
The application chemists of the METTLER TOLEDO Analytical Chemistry market support group have prepared more than 800 of ready-made analytical chemistry applications for use with the wide range of METTLER TOLEDO instruments.
It is informative to point out that the ingenious utilization of a cyclicdimerofl-lactic acid (l-LA) rendered the commercial production of high-molecular-weight, highly isotactic polylactide (PLA)52, but the efforts in attempting the chemical synthesis of high-molecular-weight, highly isotactic P3...
