摘要:
A thermoplastic resinous composition comprising a blend of:(a) 50-99 wt % of a polyester compound containing a dicarboxylic acid component, said dicarboxylic acid component to include at least 50 mol % terephthalic acid, and a glycol component including at least 50 mol % 1,4-butanediol;(b) 50-1 wt % of .alpha.-olefine copolymer; wherein the weight percentages are based on the total weight of the polyester and .alpha.-olefine copolymer;(c) 0.1-20 parts by weight of an epoxy compound having one or two epoxy groups attached to a molecule, the proportion of said epoxy compound to be based on the blend of the polyester and .alpha.-olefine copolymer.This composition exhibits a desirable combination of bonding strength and processability, that makes it suitable for use in hot melt coatings and adhesives.
摘要:
Laminated polyester film having a base layer of biaxially oriented polyethylene terephthalate or polybutylene terephthalate is laminated directly by heat sealing and without the use of any intervening adhesive with a crystalline butylene terephthalate or hexylene terephthalate copolyester blended with from about 10 to 40 weight % of a polyethylene terephthalate or polybutylene terephthalate, said copolyester containing about from 50 to about 80 mole % of terephthalic acid units based on the total acid component of the copolyester.
摘要:
A polymeric-shaped article for use as film such as microfilm, overhead projector film, reprographic film, layout base, etc., and for insulating capacitors, which has excellent transparent, slippery and dielectric properties, and the process for realizing the same, the polymeric-shaped article having a polar surface such as polyester, polyamide, polyolefins, polyimide, polyvinyl alcohol, polyethylene terephthalate or polyethylene-2,6-naphthalate, to which is bonded a multiplicity of nodules of TiO.sub.2, each nodule having a diameter in the range of from about 0.01 to about 10 .mu.m, a height or thickness in the range of from about 0.01 to about 0.5 .mu.m, and an area ratio of TiO.sub.2 to total surface of from about 0.01 to about 50%; and the process being that of exposing at least one side of the surface of the article to water vapor and bringing a tetrafunctional titanium compound such as TiCl.sub.4, tetraethyltitanate, tetraisopropyltitanate, tetra-n-butyltitanate or mixture thereof, into contact with the surface, the processing temperature being at least greater than 30.degree. C.
摘要:
A diffusion transfer photographic film, in which a film of a polyethylene terephthalate copolymer is a part of the constituents thereof, the polyethylene terephthalate containing about 3 to about 20% by weight of a polyalkylene glycol, as a glycol component comonomer, based on the weight of the polyethylene terephthalate copolymer.
