The present invention provides a copolyester resin composition which has good physical properties, biodegradability and processability and a process for preparing and/or producing the same. To improve the biodegradability and physical properties of the copolyester, the present invention applied multi-stage reaction step, and copolyester resin having number average molecular weight of from 30,000 to 70,000, weight average molecular weight of from 100,000 to 600,000, melting point of from 55&deg; C. to 120&deg; C., and melt index of from 0.1 to 30 g/10 minute (190&deg; C., 2,160 g) is obtained. The processability and physical properties of the copolyester resin of the present invention has been greatly enhanced by incorporating (i) an &ldquo;aromatic-aliphatic prepolymers&rdquo; having number average molecular weight of from 300 to 30,000 and the contiguous repeating unit of aromatic group in the dicarboxylic acid position of &ldquo;aromatic-aliphatic prepolymers&rdquo; is less than 5. Thus it can be processed by using the conventional processing equipment for polyethylene and polypropylene without any modification.

Copolyester resin composition and a process of preparation thereof

An aromatic group containing copolyester resin composition which has good biodegradability and physical properties, wherein; (i) 0.1 wt % to 30 wt % of an aliphatic prepolymers having number average molecular weight of from 300 to 30,000; (ii) one or a plurality of aromatic dicarboxylic acid (or an acid anhydride thereof which containing aromatic group in the molecule; (iii) one or a plurality of aliphatic (including cyclic type) dicarboxylic acid (or an acid anhydride thereof); and (iv) one or a plurality of aliphatic (including cyclic type) glycol, wherein the copolyester resin has number average molecular weight of from 30,000 to 90,000, weight average molecular weight of from 100,000 to 600,000, melting point of from 70&deg; C. to 150&deg; C., and melt index of from 0.1 to 50 g/10min. (190&deg; C., 2,160 g), and the process for preparing and/or producing the same. The composition and preparation method provides a high molecular weight copolyester resin which has good biodegradability and physical properties required for packaging film, trash bags and agricultural film.

The present invention relates to a high molecular weighted biodegradable polyester resin which can be used in medical, agricultural and fishery packaging materials by enhancing the low heat-resistance of the general aliphatic polyester and the preparing method for them. The present invention provides a polyester resin which is prepared by condense-polymerization after one or a plurality of condensation, esterification and ester-exchange reaction with main ingredients of (1) an aliphatic (including circular aliphatic) dicarboxylic acid (or an acid anhydride thereof) including an adipic acid, (2) an aliphatic (including circular aliphatic) glycol at least selected from one of 1,4-butanediol and ethyleneglycol with a little of a monomer including one or a plurality of an amine radical from 0.1 to 30% by weight which is about theoretical polyester weight acting as a functional radical, wherein the polyester resin has a number average molecular weight of 30,000 to 70,000, a weight average molecular weight from 160,000 to 600,000, a melting point from 45.degree. C. to 60.degree. C. and a melt flow index from 0.1 to 50 g/10 min(190.degree. C., 2,160 g) and the process for preparing and/or producing the same.

Polyester resin and a process for preparing the same

The present invention relates to a cephalosporin compound represented by the following general formula (I), its pharmaceutically acceptable non-toxic salt, physiologically hydrolyzable ester, hydrate or solvate, or isomers thereof, which is useful as an antibiotic agent: ##STR1## in which R.sup.1 represents hydrogen or an amino-protecting group,

Cephalosporin antibiotics and processes for preparation thereof

A method for making a polycrystalline silicon (p-Si) thin film by heat treating an amorphous silicon (a-Si) thin film using a laser beam, including the steps of forming an a-Si thin film over a substrate, forming a metal reflection film over the a-Si thin film, forming, in the metal reflection film, windows each having a width smaller than the width of the regular strong energy portion of laser beam, annealing the portions of a-Si thin film disposed beneath the windows using a laser beam, removing the remaining portions of metal reflection film, each having a width smaller than the width of the regular strong energy portion of laser beam, to expose the portions of a-Si thin film disposed beneath the remaining portions of metal reflection film, and annealing the thus exposed portions of a-Si thin film disposed beneath the remaining portions of metal reflection film. A plurality of microlenses are formed disposed above edges of the portions of the metal reflection film remaining after the formation of the windows. Each microlens serves to refract the energy strength of the peripheral portion of laser beam toward the regular strong energy strength portion of laser beam and thus scatter the energy strength of the peripheral portion of laser beam.
