摘要： PURPOSE:To obtain the titled polymer having improved thermal stability, by copolymerizing trioxane with a cyclic ether, supplying the crude copolymer to an extruder having plural vent ports and two or more screws and kneading the copolymer with a kneading disk paddle between said vent ports. CONSTITUTION:Trioxane is copolymerized with a cyclic ether having C-C bond in the molecule (e.g. ethylene oxide), and the obtained crude oxymethylene copolymer is supplied to an extruder having plural vent ports and two or more screws through the raw material feeding port 1. The fed copolymer is kneaded with the kneading disk paddle attached to the extrusion shaft between the first vent port 2 and the second vent port 3 to effect the decomposition of the unstable terminal of the oxymethylene copolymer. The gaseous decomposition product is discharged from the vent port to obtain the objective stabilized copolymer.

摘要： PURPOSE:To produce a specific block copolymer having excellent lubricity and antistaticity, either by the homopolymerization of formaldehyde or by the copolymerization of formaldehyde, etc. with a cyclic ether, in the presence of a specific polymer as a molecular weight regulator. CONSTITUTION:The objective block copolymer having a number-average molecular weight of 10,000-500,000 and composed of a polyacetal and the siloxane- alkylene oxide polymer having the structure of formula is produced either by the homopolymerization of formaldehyde or by the copolymerization of formaldehyde, trioxane or polyoxymethylene with a cyclic ether, in the presence of a siloxane-alkylene oxide polymer of formula (R1 and R2 are H, alkyl or phenyl; X is 0 or methylene; a and b are 1-1,000; n is 2-6) having 1-2 hydroxyl groups, carboxyl groups or amino groups at the chain terminals (e.g. dimethylsiloxane-ethylene oxide).

摘要： PURPOSE:To obtain a polyacetal having arbitrarily controllable molecular weight and excellent fluidity and impact resistance, by carrying out the anionic polymerization of formaldehyde in the presence of a polyfunctional compound containing >=3 carboxyl or amino groups. CONSTITUTION:The objective polyacetal is obtained by the anionic polymerization of formaldehyde usually in an organic medium (e.g. n-hexane) in the presence of a polyfunctional compound containing >=3 carboxyl groups or amino groups (preferably polycarboxylic acid compound or polyamine compound) as a molecular weight regulator, and if necessary, in the presence of a polymerization catalyst (e.g. dibutyltin dimethoxide). The polymerization is carried out e.g. by blow polymerization, solution polymerization, etc.

CONSTITUTION: An aldehyde copolymer consisting of 1W99mol% 4,4,4-triphenylbutanal units of formula I and 99W1mol% aliphatic aldehyde of formula II(wherein R is alkyl, haloalkyl, aralkyl, or haloaralkyl) and having a number- average MW of 1,000W5,000,000 can be easily dissolved in various solvents, for example, organic solvents such as toluene. The resulting solution can be formed into various moldings, such as films, fibers, or sheets, or can be used as such as paint for forming protective films on various bases, or as an adhesive for metals. In addition, it can be used usefully as a photosensitive material or an electron beam resist material.

摘要： PURPOSE: To obtain continuously a high-quality polyacetal, by uniformly mixing, trioxane with a Lewis acid or mixing these with a cyclic ether under heating and feeding them maintained in a liquid phase to a polymerizer.
CONSTITUTION: In the continuous polymerization for obtaining polyacetal by the homopolymerization of trioxane in the presence of a Lewis acid as a catalyst or the copolymerization of trioxane with a cyclic ether in the presence of the catalyst; the trioxane is mixed uniformly with the Lewis acid, or these are mixed uniformly with a cyclic ether at 64W140°C for 10W300sec, and the mixture maintained in a liquid phase is fed to a polymerizer. Preferably an agitator-mixer, static mixer, or double-shaft reactor is used. When an agitator-mixer is used, the distribution of a dwell time tends to be widened, so that it is preferred to use an agitator-mixer adapted to provide a sharp distribution of the dwell time.
