A composite particulate material for resin reinforcement which comprises an inorganic particulate material (A) and an elastic polymer (B) having a glass transition temperature of -10.degree. C. or below and also having functional groups capable of forming chemical bonds with resins to be reinforced, said components (A) and (B) accounting for 50-99 wt % and 50-1 wt %, respectively, of their total amount. A process for producing said composite particulate material. A reinforced resin composition incorporated with said composite particulate material. The resin composition yields molded articles which are improved in mutually contradicting properties (that is, impact strength vs. stiffness and elongation at break vs. heat resistance) and which have mechanical properties with less anisotropy. It offers good characteristic properties which are hardly attained by conventional engineering plastic materials.

Composite particulate material for resin reinforcement, production

A photosensitive polymer composition containing 0.01% to 10% by weight of a photosensitizer and, the following components A and B, is presented.

Photosensitive polymer compositions comprising polyether-ester amides

Provided is a polyether-ester-amide consisting essentially of about 5 to 50 weight percent of polaymide segment (A) and about 95 to 50 weight percent of polyether ester segment (B), and having a melting point not lower than 160.degree. C., a Shore hardness in the range of 80A to 45D, a tensile modulus in the range of 100 to 1,000 kg/cm.sup.2 and an elastic recovery at 50% elongation of not less than 70%,

Polyamide elastomer

An improved polyether-ester amide is prepared by mixing (A) an aminocarboxylic acid, (B) a poly(alkylene oxide)glycol having a number-average molecular weight of 300 to 6,000 and (C) a dicarboxylic acid at such a mixing ratio that the amount of the component (B) is 5 to 90% by weight based on the total amount and the amino, carboxyl and hydroxyl groups in the mixture satisfy the following requirement:
